Abstract
A case for a mobile device that can include a piezoelectric component that is configured to output current in response to external pressure applied to the case, a switch between a near-field communication (NFC) antenna and an NFC circuit, and a controller that is configured to be powered by the current from the piezoelectric component to open the switch after an amount of time during which the switch is closed after the external pressure stops being applied to the case.
Claims20
A case for a mobile device that comprises:
- a piezoelectric component that is configured to output current in response to external pressure applied to the case;
- a switch between a near field communication (NFC) antenna and an NFC circuit;
- and
- a controller that is configured to both:
- be entirely powered by the current output from the piezoelectric component;
- and
- control the switch (i) to stay closed during an amount of time after the external pressure stops being applied to the case and (ii) to open after the amount of time.

A method comprising:
- outputting, by a piezoelectric component, a current in response to application of external pressure to a case;
- controlling, by a controller that is entirely powered by the current output from the piezoelectric component, a switch between an NFC antenna and an NFC circuit to stay closed during for an amount of time after the external pressure stops being applied to the case;
- and
- opening, by the controller, the switch between the NFC antenna and the NFC circuit after the amount of time after the external pressure stops being applied to the case.
