Abstract in another language

Kinetic energy harvesters convert vibration energy to usable electrical energy. They work best when adapted to their environment. In particular, the resonance frequency of a resonant harvester should match the vibration frequency; otherwise, the harvested power decreases sharply. It is therefore important to know the vibration characteristics of the environment as well as possible. This work concerns itself with vibrations in domestic environments such as passive vibrations of solid structures like walls and ceilings or active vibrations of household devices. Particular attention is given to time-variant vibrations, i. e., to vibrations the characteristics of which vary with time. The results lead to guidelines for the mounting of kinetic energy harvesters and for useful harvester designs. We also present a sub-10-μW wireless sensor node for domestic temperature measurement. The small power consumption means that vibrations with small acceleration amplitudes suffice to power it via kinetic energy harvesting.
