Original Kurzfassung:
Currently energy batteries are used for the energy supply
of mobile electronic systems and devices. This solution,
however, involves expensive maintenance and raises the
question regarding final recovery and disposal. One
possible alternative to overcome these problems could be
to harvest the required energy from the environment.
In this paper we focus on harvesting mechanical energy
particularly from vibrations of cargo containers. In the
literature many miniaturized energy harvesters up to
1 mW output power are discussed. Furthermore, we will
report the essential theory as the base for the final design
of our energy harvester and a verification of a simulation
model (Matlab/Simulink) by real measurement results.
The energy harvester presented below gains an electrical
power of 15 mW on a power matched ohmic load of
25 Ohm. Further characteristics of the harvester are a
resonance frequency of 4.5 Hz, a seismic mass of 2.2 kg
and an oscillation amplitude of the seismic mass relative
to container frame (base) of 6 mm.
