Abstract
A magnetic tunnel junction (MTJ) based sensor device includes a MTJ element and processing circuitry. The MTJ element includes a free layer, a pinned layer, and a tunnel barrier, the tunnel barrier being arranged between the free layer and the pinned layer. The free layer is adapted to flex away from the tunnel barrier during acceleration. The processing circuitry is configured to measure a resistance at the MTJ element and determine acceleration based on the resistance at the MTJ element.
