  • Field Evaluations of a Damped MEMS Shock Sensor
    Results from pyrotechnic, penetration and metal-to-metal impact field evaluations are presented which prove the performance of a new piezoresistive (PR) shock accelerometer. The microelectromechanical systems (MEMS) sensor incorporates sufficient squeeze-film damping to reduce resonant
  • Development of a Damped Piezoresistive MEMS High Shock Sensor
    Piezoresistive (PR) silicon accelerometers with micro-electromechanical systems (MEMS) technology are preferred in many high shock impact measurements. These devices exploit the strength of single crystal silicon (SCS) along with the minimal zero shifting associated with PR sensors. However
  • Why is MEMS the Preferred Technology for High Shock Measurement?
    associated with high-amplitude,. high-frequency mechanical shock. An unsung hero, a chemist named. Ralph Plumlee at Sandia National Labs, researched this phenomenon. In 1971 Plumlee issued a 73 page report distributed to manufacturers. of shock accelerometers detailing the dipole switching mechanisms
  • How High in Frequency Are Accelerometer Measurements Meaningful
    Almost all piezoelectric accelerometers in the current market place. have a fundamental sensor resonance below 100 KHz. In 1983. Endevco Corporation designed a series of MEMS (Micro Electro-. Mechanical Systems) accelerometers [1]. These silicon-based. piezoresistive accelerometers enabled sensor
