Abstract
A timer for measuring a time lapsed during an acceleration is disclosed. The timer may include a piezoelectric sensor, an energy storage device and a measurement module. The piezoelectric sensor includes a piezoelectric material for generating an electric potential in response to the acceleration. The energy storage device is electrically coupled to the piezoelectric sensor and is configured for receiving the electric potential generated by the piezoelectric sensor. The measurement module is electrically coupled to the energy storage device. The measurement module measures the electric potential received at the energy storage device and determines the time lapsed during the acceleration based on the electric potential received at the energy storage device.
