Hearables body temperature monitor flex PCB strip reference design
Description
This reference design demonstrates how to use the TMP117 to measure accurate body temperature through the ear from a hearable design. This design implements two TMP117 parts on a small flexible that is suitable for hearable devices. Two temperature sensors are integrated onto the design to compensate for system or ambient temperature changes that can affect the accuracy of body temperature measurements.
