Description

This reference design demonstrates using the TMP117 to measure accurate body temperature through the ear from a hearable design. This design implements two TMP117 devices 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 the body temperature measurements.
