Power generation unit, electronic apparatus, transportation device, and method of controlling power generation unit

A method of controlling a power generation unit including

• a deforming member adapted to deform while switching a deformation direction,
• a first piezoelectric device provided to the deforming member,
• a second piezoelectric device provided to the deforming member,
• an inductor electrically connected to the first piezoelectric device, and
• a switch disposed between the first piezoelectric device and the inductor;
• the method comprising:
• detecting a current generated in the second piezoelectric device;
• and
• connecting the first piezoelectric device and the inductor electrically to each other via the switch based on the detection result of the current.

A power generation unit comprising:

• a deforming member adapted to deform while switching a deformation direction;
• a first piezoelectric device provided to the deforming member;
• a second piezoelectric device provided to the deforming member, and adapted to generate electrical power, an amount of which is smaller than an amount of electrical power generated by the first piezoelectric device;
• an inductor electrically connected to the first piezoelectric device;
• a switch disposed between the first piezoelectric device and the inductor;
• and
• a control section adapted to detect a voltage generated in the second piezoelectric device, and if the voltage detected has a level one of equal to and higher than a predetermined level, electrically connect the first piezoelectric device and the inductor to each other using the switch.
