Talented and motivated

The team

We are a multidisciplinary team with talented and motivated people. We focus on making a difference for the industry by reducing the complex challenge of powering industrial sensors to a simple and easy to use product that will enable IIoT beyond what it is capable of today.
This requires a cross disciplinary team with insight in:  

  • State-of-the-art materials chemistry
  • Ultra-low-power electronics design
  • IoT and IIoT applications
  • Technical understanding of processes and machinery
  • Cross disciplinary organizational and business development skills.

TEGnology has gathered all these abilities and expertise in the core team:

Hao Yin, CEO, hao@tegnology.dk
Hilde Seglem, CCO,  hs@tegnology.dk
Jörg Rehder, Sales & Product Management, jre@tegnology.dk 
Flemming B. Hansen, fbh@tegnology.dk
Rafael Jeppesen, Material Specialist, rafael@tegnology.dk

Li Han, Development Engineer, lh@tegnology.dk
Dahlia Dry, Engineering Intern, dahlia@tegnology.dk

Diversity and Inclusion

We believe equal opportunity is extremely important and every employee is unique in their own way. From our very beginning, we have strived to create an open, inclusive, and equal environment in which we are promoting diversity, as we believe a diverse workforce creates a better working environment and a more profitable business. Diversity includes gender diversity, cultural diversity, religious diversity, language diversity, different education levels, different viewpoints, and unique abilities.

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 took 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 have a strong belief that we can provide a sustainable power solution to these sensors at lower cost of ownership and minimum environmental footprint.
