Abstract
A magnetic tunnel junction (MTJ) based sensor device includes a first MTJ element, a first reservoir, a second MTJ element, a second reservoir, and processing circuitry. The first reservoir includes first particles configured to move within the first reservoir during acceleration. A first portion of the first reservoir is electrically coupled to a free layer of the first MTJ element. The second reservoir includes second particles configured to move within the second reservoir during acceleration. A first portion of the second reservoir is electrically coupled to a free layer of the second MTJ element. The processing circuitry is configured to determine an acceleration based on a first output voltage at a pinned layer at the first MTJ element and a second output voltage at a pinned layer at the second MTJ element.
