As the demand for technological advances increase on daily basis, so does the dependency on existing fossil fuels, which is depleting at an alarming rate. The work presented in this paper addresses key solutions to energy management, and particularly energy harvesting for powering electronic devices and sectors in general, particularly applications where components are exposed to severe subzero temperatures. This research compares the energy output in terms of voltage for 3 piezoelectric smart materials, ceramic based PZT (Lead, Zirconate Titanate), polymer membrane PVDF (Polyvinylidine Fluoride) and foam based PP (Polypropylene). Impact analysis using concentrated mass of 1.02kg from a fixed height of 17mm was allowed to drop roughly in the centre of piezoelectric material samples as the temperature was increased from approximately -33°C to room temperature. Voltage output was recorded at various temperature increments using pico-scope software, which indicated that generally, voltage increased for all 3 materials as temperature decreased.
