Human Skin Temperature Sensing for Wearable Applications Reference Design

TIDA-00824

Design files

Overview

TIDA-00824 features LMT70 analog temperature sensor for measuring human skin temperature. This reference design shows how to mechanically mount the temperature sensor for best thermal conductivity. Signal path considerations on how to achieve greater than 0.1°C accuracy is also discussed in this design.

Features
  • How to use LMT70 temperature sensor to measure human skin temperature
  • Ideal signal path components to achieve high thermal accuracy
  • Layout considerations for routing thermal paths
  • Mechanical case example for ideal mounting considerations
