Resumen:
Una spin-off de un centro de investigación alemán ha desarrollado nuevos generadores termoeléctricos (TEG) como fuente de alimentación independiente para actuadores y sensores inalámbricos. Los generadores convierten directamente el calor en electricidad tan pronto como se producen diferencias de temperatura. Gracias a los nuevos materiales y al proceso de producción de bajo coste, la empresa será el primer fabricante de TEG para aplicaciones a gran escala. Se buscan socios con el fin de establecer acuerdos de licencia, cooperación técnica e investigación.

Tittle:
Efficient energy harvesting for the internet of things or wireless sensors by use of innovative thermoelectric generators
Summary:
A spin-off from a German research institution has developed innovative thermoelectric generators (TEGs) as an independent energy supply for wireless sensors and actuators. TEGs convert heat directly into electric power as soon as there is a condition of differences in temperature. Due to new materials and and a low-cost production process the SME will be the first manufacturer to produce TEGs suitable for broad mass applications. They look for licence, technical and research co-operations.
Description:
Heat is everywhere - in many cases more than actually required. A German SME that is a spin-off from a research institution takes advantage of this fact and develops innovative thermoelectric generators (TEGs) that convert heat directly into electric power as soon as there is a condition of differences in temperature. The TEGs can be used even in the case of only small differences in temperature and are an independent energy supply for the internet of things or wireless sensors. Thus, in many connected devices inconvenient battery changes won´t be necessary anymore.

The SME also has managed to combine low-cost materials and industrial production methods for the first time and the resulting cost advantage will enable them to be the first manufacturer to produce TEGs suitable for broad mass applications.

Application fields of special interest are

- Energy harvesting for smart homes
Where heat is available, wireless devices of smart homes can be powered energy autonomous with TEGs. For instance, the regular and yet inconvenient battery replacements for electronic heating valves in smart homes can be avoided completely. The required electrical energy can be produced by converting a small amount of the radiator heat.

- Energy harvesting for industrial wireless sensor networks (WSNs)
WSNs are getting more and more important in industrial environments because monitoring of significant parameters helps to improve and to stabilize industrial processes and applications. Pipes or tubes with hot fluids or gas are perfectly suited for the new TEGs. Warm rotary parts of machinery can also be used to power sensors for condition monitoring. Depending on the industrial processes there are many more possibilities to harvest valuable heat which hasn´t been used yet.

In the current development phase the SME looks for industrial partners who can support them in scaling up the synthesis of organic semiconductors by developing a process suitable for mass production. In a second step the partner could then produce the materials under a licence agreement. They are also looking for industrial partners (OEMs, supplier) for field testing who are interested in integrating the new TEGs into their products. Furthermore, they are looking for partners active in research and development in the field of thermoelectrics and low power applications. Finally the SME looks for electronic companies supporting them with the development of very low power electronics by supplying samples and test kits. These co-operations could be performed in the frame of a technological or research co-operation.
Advantages and Innovations:
- The new TEGs are much less expensive than conventional TEGs which require rare as well as toxic materials and complex production processes.

- The new technology makes use of inexpensive organic semiconductors (electrically conductive polymers) that can be processed on large scale industrial production machines (roll-to-roll printing machines). This combination leads to a competitive price of TEGs for the first time (target PPU 1,50-Y-euro;).

- The use of polymers (plastics) confer superior mechanical, thermal and electrical properties to the new generators.

- The TEGs are only the size of a sugar cube.

- TEGs work completely maintenance-free.

- They are very flexible and can even be mounted on round surfaces like pipes which are often an ideal heat source.

- They are only made of nontoxic materials that allow for an eco-friendly disposal.

- The TEGs are made of elastic materials and therefore meet the requirements for rough industrial environments. Vibration and shocks are e.g. unable to harm the TEGs.
