University Spin-Out
The history
TEGnology is a spin-out from Aarhus University and has worked closely with researchers from Aarhus University and other top research institutes in Europe to develop an energy harvesting technique based on new and unique materials that convert waste heat into electricity.
TEGnology was originally established in 2010 by researchers at Aarhus University but was a dormant company until late 2019, when Hao Yin decided to buy out the other founders and make the technology commercially available to the market.
In 2021 TEGnology made the strategic decision to enter the solution market based on thermal energy harvesting, with focus on digitalization of the process monitoring industry. The company now operates out of the Alfa Laval Innovation House in Søborg.
IoT and Industry 4.0 have moved from “nice to have” to a “must have”. Along with increasing demands on process efficiency, lower CO2 footprint, safety assurance and life-cycle-tracking, the number of industrial wireless sensors is increasing significantly. In TEGnology we believe we can provide a sustainable power solution to these sensors at lower cost of ownership and minimum environmental footprint.
