Body-worn monitor

This invention describes a wristband that monitors movement and temperature using built-in sensors. A clever power system detects when the wristband is being worn and automatically switches between a low-power sleep mode and an active monitoring mode to save battery. Specifically, it measures body temperature and can even calculate the difference between your body temperature and the surrounding air.

Why it matters: Filed before the maturation of low-power wearable microcontrollers and integrated sensor platforms. The complex sensor fusion and power management logic described are now significantly easier to implement with off-the-shelf components and established software libraries.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: ModeratePower management, sensor fusion, custom electronics.
