(PhysOrg.com) -- Among the many applications of flexible thermoelectric materials is a wristwatch powered by the temperature difference between the human body and the surrounding environment. But if you wanted this watch made of low-cost carbon nanotube (CNT)/polymer materials, you would currently need a piece of fabric with an area of about 500 cm2, which is about 50 times greater than the area of a typical wristwatch.
