Abstract

The global reliance on fossil fuels and natural gas, has largely dominated the energy production field, but due to finite resource depletion and escalating greenhouse gas emissions, the immediate exploration of sustainable energy alternatives to mitigate climate change and ensure resource security has been a major concern. There has been extensive research into other more renewable methods of energy production such as wind and hydropower. Of these current energy generation types there are many areas of untapped potential from the mechanical movements generated ambiently not only in the large scale of power generation but also on a smaller scale. The Piezoelectric and Triboelectric effects are known phenomenon where these ambient mechanical movements can become a power generation source that produces electrical energy. The creation of a hybrid system to take advantage of both the machinal stress and surface charges present offers an ideal opportunity to take advantage of these untapped sources of energy. The production of a hybrid PVDF-HFP/PEO film with the perovskite BaTiO3 allows for the ambient power harvesting of both mechanical movement and surface charge. In combination it was seen that at 8 wt.% a voltage of up to 18 Volts and a current of 200nA with a 68K ohm resistor was recorded alluding to substantial increase from a base system having a 2.1 Volt average and 40nA. The use of these hybrid TENG’s allows for energy harvesting in small scale applications such as health monitoring devices and indicators in electric circuits.
