Summary of the technology

The present invention is a thermoelectric supercapacitor able to produce energy from the dissipation of heat and simultaneously able to store the produced energy. The device is designed on a flexible substrate, and with a 2D planar configuration, and it is composed of two closely spaced nano-structured electrodes separated by a polymer solid-gel electrolyte. The combination of energy harvesting (thermoelectricity) with energy storage (supercapacitance) in a single and flexible device, allied with the low-cost production and possibility to scale up, makes the present technology attractive for several applications such as wearables, smart clothing, health and well-being, sports and transport sectors.

Details of the Technology Offer

By combining thermoelectricity and super capacitance phenomena in a single device, it is possible to harvest the waste heat released by the human body or any type of machine, into electrical energy and simultaneously to store it, to be reused to power small electronic devices. The unique characteristics such as flexibility, lightness, non-toxicity, all solid-state materials and possibility to scale up, make the present technology attractive for several applications where heat dissipation may occur, such as: wear, health, transport-sector or electronicsensors industry.
