The Future of Wearable Technology

The limiter to real-time physiological status monitoring (RT-PSM) has not been engineering technology. More than 50 years ago, John Glenn blasted off from Cape Canaveral while his medical team monitored a modest heart rate increase to 110 beats per minute. This ability to remotely monitor physiological signals has improved in terms of size, weight, comfort, cost, and power. Today, for example, recreational athletes commonly monitor their heart rate with commercial body-worn systems.
