Accelerometer and Gyroscope Designs Based on Carbon Nanotube Tape

NASA Marshall Space Flight Center developed designs for two micro-electromechanical systems (MEMS) motion and position sensors: a single-axis accelerometer and a gyroscope. The designs leverage a highly aligned multi-wall carbon nanotube (MWCNT) tape with a P(VDF-TrFE) matrix that is mechanically robust and has excellent piezoelectric properties as the sensing and actuating element.
