Following the motto "no batteries, no cables", Hahn-Schickard develops the smallest energy generators that supply wireless sensors and mobile systems directly with energy from the environment. Cables, rechargeable batteries and batteries become superfluous and new applications are opened up.

Hahn-Schickard is pursuing various approaches for generating energy from the immediate environment of electronic systems: Movements and vibrations of machines, impacts and forces or even the waste heat of devices provide the power required for operation.

The aim of the current research projects is to develop energy systems for e.g. wireless radio sensors, entire sensor networks or hidden, difficult-to-access sensor applications as well as mobile applications of all kinds. These allow complete autonomy, enable theoretically unlimited operating time and the greatest possible freedom from maintenance.

In the long term, they should make the power supply of sensors and actuators through electrical cables or batteries superfluous. Microgenerators harvest power from their environment. Solutions pursued by Hahn-Schickard combine capacitive, inductive, piezoelectric and thermoelectric microgenerators and bio-fuel cells.
