Designing Feature-Rich Wearable Health and Fitness Devices

Wearable devices are transforming everything from remote patient monitoring to fitness tracking and hearing assistance. The next step is to shrink the size of these devices while offering more comfortable shapes and additional features and wireless communications capabilities. The biggest obstacle is the battery, and more specifically the Lithium-ion (Li-ion) batteries used in the majority of wearables. Today’s devices have been tethered to the form-factor and performance limitations imposed by these batteries’ liquid electrolyte chemistry.
