  • Spintronic mechanical shock and vibration sensor device
    Patent number: 10871529
    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, an elastic layer, and a tunnel barrier. The free layer is spaced apart from the pinned layer by the tunnel barrier and the elastic layer. The processing circuitry is configured to measure a resistance at the MTJ element and determine whether mechanical shock and vibration has occurred based on the resistance at the MTJ element.
    Type: Grant
