Miniaturized medical device having a wake-up device

A method for operating a miniaturized medical device, comprising:

• providing an electronic functional device for performing a function of said miniaturized medical device, said functional device having an operational state for performing said function and a switched-off state;
• and providing a wake-up device for transferring said functional device from said switched-off state to said operational state, wherein generating a wake-up signal for waking up said functional device using an electrical detection circuit of the wake-up device and a switch device arranged in the electrical detection circuit, the switch device comprising a switch member, a magnet device, wherein the magnet device is connected to or attached to the switch member, and a contact element attached to the switch member and at least one switch contact associated with the electrical detection circuit;
• wherein the generating of the wake-up signal includes exciting the switch member by a time-varying magnetic field to perform an oscillating movement, wherein the switch member is a mechanical resonant system having a resonant frequency and, due to oscillating movement corresponding to the resonant frequency, causes the contact element to cycle between contact and non-contact with said at least one switch contact to perform a switching action of the switching device in the electrical detection circuit for generating the wake-up signal, wherein the magnet device oscillates with the switch member.
