Abstract
A wake-up unit for waking up an electronic device is provided. The wake-up unit comprises a resonating unit (C) for resonating at least one specific frequency, at least one first electrode (TE), at least one piezoelectric material (PM) and at least one second electrode (BE). The piezoelectric material (PM) is sandwiched between the at least one first and the at least one second electrode (TE, BE) such that an electronic current is provided to the at least one first and at least one second electrode (TE, BE) when the resonating unit (C) resonates at the at least one specific frequency.
