I would like help in designing a small piezoelectric switch on the order of 6mm square using a thin piece of piezo film that could detect a small pressure e.g. a few grams and give a clean pulse output. It would be good if the circuit would be very energy efficient also since it will be used in a battery operated device.
I am seeking an electrical designer with experience with transistor and op amp circuits to design, breadboard, test, and supply me with schematic so I can duplicate the same.
