I Particle accelerometer

  1. Feb 11, 2019 #1
    Hi everyone. I want to make a very small accelerometer. (A micro or nanosized MEMS accelerometer)

    What do you think about this idea?

    I will have a source which will emit alpha particles. I will place two movable magnets at both sides of the alpha particle. When I apply acceleration to the sensor, the magnets will move (due to inertial fictious force) and alpha particle will deviate from its path. The deviation will be a related to acceleration.

    How would a charged particle behave inside a moving magnetic field?

    How small I can make this accelerometer you think? (Also please share if you have any ideas about making the world's smallest MEMS accelerometer)

    Thank you.

    (PS: I know how today's accelerometers work. I just want to come up with a creative idea)

    There are so many ways to measure the position of an object with high precision. The deviation of the flight of alpha particles is not among them. Even state-of-the-art pixel detectors will have a hard time measuring any deflection on such a small scale, and that's not even considering the problems from getting a focused beam, getting enough statistics, removing background and so on.
