Re: April 17 – DAY 3: Energy Generation Discussion 2

NO RATINGS
Piezo devices:  Low frequencies may indeed generate higher

power.  Voltage is dependant upon the time-rate-of-change of

a single deflection.  If the device has a heavy load, then that

change will happen rapidly and be large - potentially generating

a voltage spike.  If the vibration-energy is period, then so will be

the output.  If an impulse is applied to the device - that will show

up as an impulse energy on the output.
