Electromagnetic generator for converting mechanical vibrational energy into electrical energy in e.g. temperature sensor, which is utilized for measuring e.g. heart rate, has input nodes for collecting energy generated by induction

摘要

The generator has coils e.g. vertically directed coils (5, 6), diagonally directed coil (10) and horizontally directed coil (12), and multiple electromagnetic masses e.g. permanent magnets (2), which are movable relative to each other along the different spatial directions. A voltage is induced in the coil by the relative movement of the coils and the masses. An electronic switch has input nodes, which are connected with the coil, to collect electrical energy generated by induction, and output nodes at which the collected electrical energy is regulated. An independent claim is also included for an autonomous wireless sensor comprising an electromagnetic energy collecting device.
