This so-called Peltier effect also helps cool electronic device such as laptops.
But such heat-exchange devices need fans to blow away excess heat. However, Vistakula used nanomaterials to create a super small version of the device with no moving parts and is built into lightweight plastic tiles within the jacket.
The tiles are powered by rechargeable batteries that can hold 8 hours on a single charge. The jacket weighs just over one pound and can maintain internal temperatures between 68 to 104 degrees Fahrenheit and can operate in ambient temperatures between -122 and 122 degrees Fahrenheit.
Besides ClimaWare jackets, the company also sells neck wraps, shoes, and bike helmets, as well as knee and elbow packs that provide hot and cold therapy. Vistakula's 20-person team has their sights set on "HaemoSave", an application that could utilize freezing temperatures to control bleeding, pain and inflammation during medical emergencies.
