A team of researchers at the University of Washington (UW) has created a flexible electronic prototype capable of generating electricity using only body heat.<\/strong> This elastic prototype can power small electronic devices, such as LEDs, and is resistant to punctures and stretching, maintaining its functionality even after being stretched more than 2,000 times.<\/p>\n\n

The breakthrough, presented in the journal Advanced Materials<\/em><\/a><\/strong>employs thermoelectric technology that efficiently converts body heat into electricity.\nTraditionally, devices that use thermal energy have been rigid and fragile, making them impractical for use on the skin.\nHowever, this new UW prototype is highly flexible and adaptable, allowing it to adhere comfortably to the skin, making it ideal for wearable applications. <\/p>\n\n

Design of the flexible electronic prototype<\/h2>\n\n

The team led by Mohammad Malakooti, assistant professor of mechanical engineering at the UW, designed this device using simulations to find the best materials and structures to optimize energy conversion.\nThe device consists of three main layers.\nAt the center, there are thermoelectric semiconductors that convert heat into electricity.\nThese layers are surrounded by 3D printed composites that enhance energy conversion. energy conversion<\/a><\/strong> and reduce the weight of the device.\nIn addition, the layers are connected by traces of liquid metal, which provides elasticity and self-healing. <\/p>\n\n

A key feature of this device is the integration of liquid metal droplets in the outer layers, which increases heat transfer and helps maintain flexibility.\nThis entire design was developed in Malakootiti’s Malakooti’s laboratory<\/a><\/strong>with the exception of the semiconductors. <\/p>\n\n
