Testing Battery Systems Designed for Wearable Technologies
The worldwide market for wearable technologies is expected to reach $70 billion (USD) by the year 2025, up from just $20 billion in
2015. This anticipated growth in the wearable technologies market depends on the continuous development of new technologies
such as wireless technology, smart electronics and advanced energy storage systems that can provide consistent and reliable power
without compromising the overall experience of the user. However, although new battery and energy storage technologies are
generally safer than many currently available alternatives, wearable technology devices incorporating them must still be thoroughly
evaluated to help identify potential safety and performance concerns.
This UL white paper discusses testing and evaluation considerations for batteries and energy storage systems used in wearable
technologies. Beginning with a summary of the historic technical challenges for wearable technologies, the paper highlights the
emergence of new approaches to powering wearable technology devices and their advantages over current technologies. The white
paper then summarizes potential safety and performance considerations for batteries used in wearable technologies, and details
specific tests that can be used to evaluate them for consistency with regulations and customer expectations. The paper concludes
with additional recommendations for the assessment of batteries and energy storage systems used in wearable technology devices.
