Abstract
Magneto-Mechanical Resonator Sensor with Mass Distribution Channel Some aspects of the present disclosure feature a sensing device (e.g. for temperature, moisture or detection of substances) comprising a magnetic bias layer, a resonator, a spacer, and an environmental change receptor. The spacer is disposed between the magnetic bias layer and the resonator. At least one of the resonator surfaces has a predefined channel. The environmental change receptor is disposed proximate to the predefined channel. In response to a change in environment, the environmental change receptor distributes along a part of the channel.
