Sensor and/or power-harvesting apparatus are provided for sensing and/or harvesting energy across a relatively wide dynamic range of a driving rotational input. The apparatus may include a rotor magnet () responsive to a driving rotational input (). Utilization of a togging effect or a magnetic spring effect results in certain rapid-rotation events where the rotor magnet can rapidly rotate regardless of a low rate of rotation of the driving rotational input. A coil assembly () is magnetically coupled to the rotor magnet to generate a signal in response to rotation of the rotor magnet during the rapid-rotation events. This signal may be used to harvest electrical energy and/or may be processed to determine characteristics of the driving rotational input.
