DEG – Dielectric Elastomer Generators

With dielectric elastomer generators novel environmentally friendly and decentralized energy supply concepts for rural areas can be developed, for example, for power supply for campsites or charging stations for electric vehicles far away from power line networks. By using low water flow that could not be utilized so far by conventional hydroelectric power plants, power plant swarms can be realized without transverse structures.


0 → 1 : initial load
1 → 2 : extension
2 →3 :
Loading by applying an electrical voltage
3 → 4 :
mechanical relax , voltage increase
4 → 1 Unloading to a defined nominal output voltage
