Nabídka technologie - Inovativní zařízení pro získání energie z tepelných zdrojů

PopisAbstract:
A Spanish research entity and two Universities from USA and Switzerland have developed a device for energy harvesting. The device comprises a set of quantum dot nanostructures located between the contacts of an electrically connected cavity. The high degree of tunability of quantum dots allows optimal harvesting of the heat generated in the cavity. The simplicity of the designed structure eases its replication in a two-dimensional distribution. Partners interested in a patent licences are sought

Description:
A Spanish research entity and two Universities from USA and Switzerland have developed a device for energy harvesting. The device comprises a set of quantum dot nanostructures located between the contacts of an electrically connected cavity. The high degree of tunability of quantum dots allows optimal harvesting of the heat generated in the cavity. The simplicity of the designed structure eases its replication in a two-dimensional distribution enhancing the generated power.

Energy harvesting is currently one of the most important technological challenges. The need of small and energetically autonomous sensors distributed throughout the environment involves the use of elements which can provide the required amount of energy to assure their working state. For this purpose the types of harvested sources can be movement, differences in temperature, light and radiofrequency emissions. The ultimate goal of this technology is to obtain perpetual devices freed of any wire connection. The uses of these devices are increasing every day being medical applications and distributed environmental monitoring the most current ones.
The designed device harvests energy from an environment at a higher temperature by converting heat to electric power. It comprises, in a basic form, a quantum dot nanostructure located between the contacts of an electrically connected cavity. This nanostructure works according to the tunnel effect and only transfers electrons at chosen energies and therefore brings about a powerful and efficient thermal engine.
The structure simplicity allows a two-dimensional replication easily achievable by current manufacturing techniques. This feature is a significant advantage for a rapid introduction to the market. Furthermore, its flexibility allows an easy embedment in any other electronic device covering a wide range of needs.

Innovations and advantages of the offer
- Estimated generated power of 1 W / cm2 for each oC difference.
- Without any moving parts. Easily embeddable in electronic devices (mobile telephones, laptops, etc.). It contributes with its cooling capacity to the surrounding elements.
- Simplicity of design provides flexibility and scalability.
