Perpetua Power Source Technologies has developed wearable technology that converts body heat into energy. Branded as TEGwearTM Technology, these sources generate enough energy to power small, wearable electronic devices.

A ready-power source, TEGwear can extend battery life by offering added energy for additional product features or functions, or replace batteries altogether in certain applications. Wireless health monitoring, sports and fitness monitoring, location awareness and other low-power, mobile consumer electronic devices may benefit from this unique energy technology.

Unlike traditional thermoelectric energy harvesters designed for high-temperature applications, TEGwear is based on a flexible design, allowing easily customizable and highly scalable configurations. TEGwear has successfully demonstrated power generation from body heat for operation of a number of consumer products, such as watches and wireless heart rate monitors. By replacing or supplementing batteries, thermoelectric energy harvesting has the ability to accelerate the use of sensors and low-power electronics throughout the world, resulting in smart systems that are more efficient and cost effective. Future applications for this technology range from on-body wireless sensor systems for medical or recreational purposes to civil infrastructure sensor systems for remote preventative maintenance monitoring...
