Abstract

Modern technologies such as factory or home automation involve the use of a multitude of sensors. The communication between the sensors and central control units can be implemented by wireless sensor networks (WSN). This concept unfolds its full potential only when the distributed sensors are energy-autarkic (no communication lines, no power lines). One possibility of powering the sensor nodes is through vibration energy harvesting. Microstructures convert energy from the mechanical to the electrical domain by, e.g., electromagnetic or piezoelectric coupling. For an efficient conversion the resonance frequency of the kinetic energy harvester should match the ambient vibration frequency. In order to select or design the most suitable harvester for a given environment, it is therefore crucial to know the details of the environment. We investigated several potential vibration sources in a domestic environment to shed more light on how smart-home sensor nodes can be powered. We not only considered vibration strengths and frequencies [1], but also the time variance of the vibration characteristics and different operation conditions. This work shows that the vibration sources available in domestic environments offer frequencies between 20 and 200 Hz and acceleration amplitudes between 10-4 and almost 10 m/s². Vibration amplitudes above 0.1 m/s², which are necessary for powering sensor nodes, are only offered by actively vibrating devices.
