Thermoelectric generators (TEG) generate electricity from any thermal
source. If one side of the TEG is warmer, or colder than the other,
electricity is generated. TEGs function without toxic substances or
moving parts guaranteeing a long, maintenance free life cycle. Energy
harvesting refers to the process in which small amounts of electricity
are generated for applications such as sensors, actuators, consumer
electronics and applications in research.
Energy harvesting utilizes existing thermal sources to generate
electricity. The thermal difference between the human body and ambient
air, or the heat emitted by a central heating tube are typical examples
of applicable thermal sources. Unlike Waste heat recovery, energy
harvesting only generates small amounts of electricity.

- Building Technology: Enhancing the energy efficiency of
Despite strongly improved materials and construction methods
buildings still make for the largest share in energy consumption. A
further reduction of the energy consumption and at the same time an
increase of comfort levels is possible with smart management of
buildings, e.g. by controlling the building as a function of the
presence/absence and activity type of the inhabitants, weather
conditions, and many more. greenTEG’s energy harvesting and heat
flux measurement technology provides solutions for enhanced energy
efficiency in building technology: The energy harvesting technology
allows to power smart sensor and actuator systems without batteries
and cables. The smart sensors help increase the energy efficiency of
buildings without adding maintenance costs for batteries and cables.
Our thermal measurement technology enables the assessment of thermal
characteristics of building materials. Learn more about heat flux
measurements in building physics
to enhance the energy efficiency of your building.
- Consumer Electronics: Increased quality of life by
thermoelectric energy harvesting
Thermoelectric energy harvesting can improve our daily life quality
by providing small amounts of electrical power to wireless sensor
nodes or consumer electronics. As a result, these applications and
devices can be run without any battery power. They are therefore
easy to use and environmentally friendly. gTEG® enables zero power
technology for consumer electronics applications. The greenTEG
Energy Harvesting Technology powers autonomous devices from body
heat. Therefore, oit can be used in devices which have a low power
consumption (max. in the uW range) and can be put close to the body
surface. Integrating gTEG® into your device is easy and saves costs.
greenTEG provides flexible thermoelectric generators (gTEG®s) for
generating power from any kind of temperature difference or heat
source. gTEG®s convert thermal energy directly into electricity
without any moving parts or toxic substances. Their shape is
customizable to specific needs which guarantees best performance at
lowest cost. By improving energy efficiency and reducing maintenance
efforts you reduce your customers total cost of ownership (TOC) and
comply with future efficiency regulations. Attractive applications
are especially around life sciences: Medical applications for
monitoring physical and physiological status, Smart textiles, Sports
applications, Real time location. systems
- Industry: Monitoring processes and making use of untapped
energy sources in industrial settings
The Factory of the Future is smart and energy efficient.
Flexible throughputs at best qualities while at the same time
ensuring cost efficiency are the key characteristics of smart
factories. Predictive maintenance helps to keep downtimes and costs
for repairs low. This is enabled by a high grade of automation. The
gSKIN Heat Flux Sensor
assesses thermal processes and supports energy efficiency projects.
The gTEG Energy Harvester powers wireless sensor nodes by low grade
heat sources. Without batteries or cables one can “deploy and
forget” these sensor nodes. In the future, greenTEG’s technology
will enable electricity generation from waste heat in industrial
settings. greenTEG’s Waste
Heat Recovery Technology is not yet commercially available.
- Research: Measure thermal flows and systems fast and with
greenTEG’s gSKIN® Heat Flux Sensor measures conductive and
convective heat flows as well as radiation fast and with high
accuracy. The small dimensions and the customizable form of the
gSKIN® make it the ideal tool in many R&D related settings, for
example the improvement of materials, the monitoring of chemical and
physical reactions, the measurement of solar radiation and laser
power among many more. greenTEG’s thermoelectric energy harvesting
technology allow you to power systems which are hard to reach and
need a continuous supply of electricity, for example in satellites.
greenTEG is currently developing energy harvesting solutions in close
co-operation with original equipment manufacturers.
