It will reset each morning, before the gates open, though the data collection is a 24 hour process. It presents the mathematical theory of materials, electrical conductivity, and device design for vibration-based harvesters, thermoelectrics, photovoltaics, wind-energy turbines, and hybrids thereof. Once the resonance frequency and the relative amplitude have been found, the bandwidth of the system can be evaluated looking for the points where the response decays of 3 dB (70.7% of the amplitude or 50% of the power). Energy harvesting from wind-induced vibrations is considered to be a promising solution for the power requirements of wireless sensor nodes. A problem for a conventional wind energy harvester is that it can only effectively harness energy from two types of excitations around its resonance frequency.

The hybrid PD harvester brings together the following two electromechanical transduction mechanisms: piezoelectric ceramic (PZT) sheets and a vibro-impact (VI) dielectric elastomer generator (DEG). The rapid proliferation of wireless sensors and microelectronics has spurred considerable interest in developing small scale devices that convert ambient energy sources to electrical power. When a periodic external force at the resonance frequency is applied to the system, its response to the excitation is a displacement of maximum amplitude (and thus the energy conversion is maximized). This energy may be stored in rechargeable batteries, or ultra-capacitors, or the device may simply provide a steady flow of electricity from constant, repetitive vibrations. Currently, the unit is the size of a 9 volt battery, but there are plans to make it even smaller. The cell can be completely sealed, making them suitable for a variety of weather conditions.
