The device shown is a Piezo transducer which will be used to create our electrical power.  

 These Piezo transducers will be sandwiched between two pieces of foam to give more mechanical strength.

 Testing the output voltages of these pads allows us to simulate the piezo effect on Multsim or Matlab/Simulink.

 Simple test watching an LED light up when pressure is applied to the Piezo Transducer.
