Phase 2

In phase 2, the electrical circuit was improvised and it was tested out using barium titanate capacitors. Barium titanate was used because it has been widely studied as a pyroelectric material and it served as a teaching tool to determine the functionality of the circuit. The circuit was also tested with and without the material present to compare the output difference. In addition, barium titanate was also characterized to improve the performance of the circuit.

The heating and cooling process of our configuration. Cooling was done with a heat sink or with a cool counter top. The changes of the Olsen Loop stage is controlled and monitored by the microcontroller.

Output measurement (real time) of the material using Signal Express.
