Stretchable Wireless Sensor Could Monitor Healing of Cerebral AneurysmsTBMG-361493/1/2020
The stretchable sensor, which operates without batteries, would be wrapped around stents or diverters implanted to control blood flow in vessels affected by the aneurysms. To reduce costs and accelerate manufacturing, fabrication of the stretchable sensors uses aerosol jet 3D printing to create conductive silver traces on elastomeric substrates. The 3D additive manufacturing technique allows production of very small electronic features in a single step, without using traditional multi-step lithography processes in a cleanroom. The device is believed to be the first demonstration of aerosol jet 3D printing to produce an implantable, stretchable sensing system for wireless monitoring.

Wireless Sensor “Stickers” Track Physiological SignalsTBMG-358231/1/2020
Engineers have developed a way to detect physiological signals emanating from the skin with sticky sensors that beam wireless readings to a receiver clipped onto clothing. To demonstrate the wearable technology, the researchers stuck sensors to the wrist and abdomen of a test subject to monitor the person's pulse and respiration by detecting how their skin stretched and contracted with each heartbeat or breath. Likewise, stickers on the person's elbows and knees tracked arm and leg motions by gauging the minute tightening or relaxation of the skin each time the corresponding muscle flexed.
Using 24 GHz Doppler Radar Sensors for Noncontact Human Vitals DetectionTBMG-3562312/1/2019
Health and wellness monitoring is a primary way to manage personal health and awareness for a healthy lifestyle. Many wearable activity tracking devices, smart watches, and smartphone applications collect and analyze data from bodily sources. Other types of devices used to monitor vital signs can help the wearer manage health issues but can limit the wearer’s mobility or cause discomfort if worn continuously. These restrictions have prompted a growing interest in developing noncontact, wireless devices to detect vital signs, especially for people who are unconscious, sleeping, very young, elderly, or infirm. This article explains why 24 GHz Doppler radar sensors are useful for such devices and highlights some of the features suitable for meeting these applications.

Hydrogel Adhesive Helps in Wound HealingTBMG-3534710/1/2019
Cuts, scrapes, blisters, burns, splinters, and punctures — there are a number of ways our skin can be broken. Most treatments for skin wounds involve simply placing a barrier over them (usually an adhesive gauze bandage) to keep it moist, limit pain, and reduce exposure to infectious microbes, but do not actively assist in the healing process. A new, scalable approach to speeding up wound healing has been developed based on heat-responsive hydrogels that are mechanically active, stretchy, tough, highly adhesive, and antimicrobial: active adhesive dressings (AADs). Created by researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University, Harvard's John A. Paulson School for Engineering and Applied Sciences (SEAS), and McGill University, AADs can close wounds significantly faster than other methods and prevent bacterial growth without the need for any additional apparatus or stimuli. The research is reported in Science Advances.
Dynamic Thermal Behavior of a GDI Spray Impacting on a Heated Thin Foil by Phase-Averaged Infrared Thermography2019-24-00369/9/2019
The regulations about pollutant emissions imposed by Community’s laws encourage the investigation on the combustion optimization in modern engines and in particular in those adopting the gasoline direct injection (GDI) or direct injection spark-ignited (DISI) configuration. It is known that the piston head and cylinder surface temperatures, coupled with the fuel injection pressure, strongly influence the interaction between droplets of injected fluid and the impinged wall. In the present study, the Infrared (IR) thermography is applied to investigate the thermal footprint of an iso-octane spray generated by a multi-hole GDI injector impinging on a heated thin foil. The experimental apparatus includes an Invar foil (50 μm in thickness) heated by Joule effect, clamped within a rigid frame, and the GDI injector located 11 mm above the surface. Thermal images of the impinging spray are acquired from the dry side of the foil at several time delays after the impact instant at two different injection pressures (10 and 20 MPa). The temperature difference distributions are employed to describe the unsteady dynamics of the impingement.

Monitor Babies in the NICU Without WiresTBMG-345816/1/2019
An interdisciplinary Northwestern University team has developed a pair of soft, flexible wireless sensors that replace the tangle of wire-based sensors that currently monitor babies in hospitals’ neonatal intensive care units (NICU) and pose a barrier to parent-baby cuddling and physical bonding. The lead researcher was John A. Rogers, a bioelectronics pioneer, who led the technology development. The team recently completed a series of first human studies on premature babies at Prentice Women’s Hospital and Ann & Robert H. Lurie Children’s Hospital of Chicago. The researchers concluded that the wireless sensors provided data as precise and accurate as that from traditional monitoring systems. The wireless patches also are gentler on a newborn’s fragile skin and allow for more skin-to-skin contact with the parent. Existing sensors must be attached with adhesives that can scar and blister premature newborns’ skin. The study, involved materials scientists, engineers, dermatologists, and pediatricians. It includes initial data from more than 20 babies who wore the wireless sensors alongside traditional monitoring systems, so the researchers could do a side-by-side, quantitative comparison. Since then, the team has conducted successful tests with more than 70 babies in the NICU.

A Comparison of Control Activity and Heart Rate as Measures of Pilot Workload in a Helicopter Tracking TaskF-0075-2019-145595/13/2019
Two qualified test pilots performed a target tracking flight task on a Bell 205 helicopter. Cooper-Harper handling quality ratings confirmed that pilot compensation was proportional to task difficulty. Pilot control activity was measured using the Dynamic Interface Modeling and Simulation System Product Metric (DIMSS-PM) to quantify the number and amplitude of control deflections during each trial. Inter-beat interval measures of heart rate and heart rate variability were also computed to evaluate the pilot's autonomic nervous system (ANS) response to task workload. The DIMSS-PM was positively correlated with task difficulty, as expected based on the dynamics of target motion for each difficulty level. By comparison, the mean and high-frequency (HF) variability of heart beat intervals were negatively correlated with task difficulty, suggesting an increase in ANS arousal with increased pilot workload. Pilot-specific differences were found in the time-dependent relationship between DIMSS-PM, mean heart beat interval, and HF variability, indicating that control activity and heart rate metrics provide asynchronous and complementary information about pilot workload during helicopter flight.

Style Meets Technology in the World of WearablesTBMG-344385/1/2019
People often talk about thinking “outside the box” but one of the things most exciting in modern technology is being able to design “off the glass” — meaning a piece of technology that isn't bound to a glass screen with a perimeter of plastic. Thanks to Moore's Law and cheap computing power, designers can embed technology into items worn on the wrist to monitor your health, or shoes that count your steps, or rings that can store data. Or, if you're me, 3D printed armor with microprocessor controlled servos to open your visor. Welcome to the world of wearable computing.
Driver Workload in an Autonomous Vehicle2019-01-08724/2/2019
As intelligent automated vehicle technologies evolve, there is a greater need to understand and define the role of the human user, whether completely hands-off (L5) or partly hands-on. At all levels of automation, the human occupant may feel anxious or ill-at-ease. This may reflect as higher stress/workload. The study in this paper further refines how perceived workload may be determined based on occupant physiological measures. Because of great variation in individual personalities, age, driving experiences, gender, etc., a generic model applicable to all could not be developed. Rather, individual workload models that used physiological and vehicle measures were developed. Unlike some existing methods of workload estimation where one, or a few signals are used, such as electroencephalography (EEG), electrocardiography (ECG), we developed intelligent systems that use multiple physiological and vehicle signals based on an end-to-end deep neural learning architecture to make a robust estimation of workload. The deep neural learning system, MTS-CNN, is designed to learn workload patterns from synchronized, heterogeneous temporal signals. All data collected for training and testing are from real-world driving trips along the same route which comprised urban local roads and highways. Data from twenty participants whose driving experience ranged from a few months to several years were collected and analyzed. The experimental results indicate that the proposed driver workload estimation model is capable of learning well from the combined temporal physiological and vehicle signals and good performance was obtained on workload estimation.

Analyzing the Limitations of the Rider and Electric Motorcycle at the Pikes Peak International Hill Climb Race2019-01-11254/2/2019
This paper describes a post-race analysis of team KOMMIT EVT’s electric motorcycle data collected during the 2016 Pikes Peak International Hill Climb (PPIHC). The motorcycle consumed approximately 4 kWh of battery energy with an average and maximum speed of 107 km/h and 149 km/h, respectively. It was the second fastest electric motorcycle with a finishing time of 11:10.480. Data was logged of the motorcycle’s speed, acceleration, motor speed, power, currents, voltages, temperatures, throttle position, GPS position, rider’s heart rate and the ambient environment (air temperature, pressure and humidity). The data was used to understand the following factors that may have prevented a faster time: physical fitness of the rider, thermal limits of the motor and controller, available battery energy and the sprocket ratio between the motor and rear wheel. Even though the rider’s heart rate implied a vigorous exercise intensity level, throttle values indicated that the rider wanted to go faster ~33% of the time. The motor reached a steady-state temperature that was approximately 30°C below the maximum allowable temperature and thus could have handled more current. By analyzing additional thermal and current data, it was concluded that the motor controller was likely a limiting factor but not the battery capacity since only ~2/3 of the total available battery energy was consumed. A model that estimates the optimal sprocket ratio was derived and validated; It was determined that using the optimal sprocket ratio of 62/12 would have decreased the finishing time by approximately 2 seconds.

Sensations Associated with Motion Sickness Response during Passenger Vehicle Operations on a Test Track2019-01-06874/2/2019
Motion sickness in road vehicles may become an increasingly important problem as automation transforms drivers into passengers. The University of Michigan Transportation Research Institute has developed a vehicle-based platform to study motion sickness in passenger vehicles. A test-track study was conducted with 52 participants who reported susceptibility to motion sickness. The participants completed in-vehicle testing on a 20-minute scripted, continuous drive that consisted of a series of frequent 90-degree turns, braking, and lane changes at the U-M Mcity facility. In addition to quantifying their level of motion sickness on a numerical scale, participants were asked to describe in words any motion-sickness-related sensations they experienced. Prior to in-vehicle testing, participants were shown a list of sensations that are commonly experienced during motion sickness: head sensations, body temperature change, drowsiness, dizziness, mouth sensations, nausea, or other sensations, which refer to difficulty focusing, irritability, eyestrain, or difficulty concentrating. Participants were instructed not to limit themselves to the list, but rather to report in their own words how they felt throughout the drive. For each sensation, they were also asked to describe the level of the sensation they experienced as mild, moderate, or severe. Chi-square analysis demonstrated that the sensations experienced were associated with in-vehicle test conditions and participant’s motion sickness susceptibility. This study is the first to continuously quantify the type, incidence, intensity, and timeline progression of self-reported sensations associated with motion sickness response during passenger vehicle operations on a test track. Sensations were multidimensional and highly variable across individuals indicating that motion sickness is a multi-faceted response that extends beyond nausea.

Modular Biosensor Patch19AERP04_084/1/2019
Identifying new biomarkers to help monitor cognition and stress in the human body could enhance human performance. Army Medical Research Acquisition Activity, Fort Detrick, Maryland Researchers are identifying new biomarkers to help monitor cognition and stress in the human body and enhance human performance. Traditional biomarkers like heart rate, temperature, oxygen partial pressure, blood glucose, electrolyte concentration, and others have been correlated with cognition and stress states. However, the correlation is indirect. Molecular biomarkers with stronger and more specific links are preferred. Molecular biomarkers can be more specific to cognition states and typically take the form of bioactive molecules including steroids, proteins, carbohydrates, lipids, and nucleic acids. The tools available to quantify molecular biomarkers during their discovery are sensitive and selective, but also have significant drawbacks. In particular, these tools are inconvenient in a variety of ways and prohibit real time monitoring. As medical researchers identify new molecular biomarkers of importance, medical professionals need wearable sensor systems to take full advantage of their discovery. The plan is to develop a modular wearable biosensor patch to provide non-invasive, continuous monitoring of sweat based biomarkers.
