Harvesting kinetic energy from human motion and converting it into usable electrical energy has become in recent years an attractive approach to powering wireless portable devices. The energy harvester developed at Fraunhofer IPMS is based on thin films of dielectric polymers of large relative permittivity. As compared with traditional piezoelectric configurations, this concept works non-resonantly and can be optimized for capturing energy from mechanical power sources in the low frequency range. Additionally, the developed device is small, flexible and easily embeddable into, for instance, the sole of a shoe. This is able to generate several µW of power in a second when subjected to mechanical deformation of pressure and frequency range specific to human walking. The harvester circuit has been adjusted to power a transmitter module. Thus the system is able to generate mechanical power and, using that, to transmit telegrams at intervals of seconds. The harvester device and circuit can be adapted for other applications such as for powering wireless sensors (temperature, acceleration, pressure), for powering portable devices and monitoring various bio-data.
