Thermal management and safety regulation of smart watches

摘要

A smart watch is one of the most popular wearable devices now. The end user cares about the electronic performance and safety. Along with the battery life and security, thermal safety is the most common concern. We show how to meet the ergonomic standard of user, predict the thermal performance on the typical scenarios. Certain thermal simulation software Flotherm or Icepack can be applied to the design stage. Heat spreading material and other thermal solutions need to be designed accordingly.
