  • Linearity Measurements for MEMS Pressure Sensors
    Pressure non-linearity is one of the parameters that impacts sensor accuracy. (For other factors, refer to All Sensors Pressure Point 2: Understanding Accuracy and Precision for MEMS Pressure Sensors.) As such, users need to understand some of the nuances involved with measuring and specifying
  • 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?
    In 1947 the first piezoelectric accelerometer was designed in the United. States1. Within 2-decades, piezoelectric accelerometers with their. higher resonant frequencies, signal levels, and amplitude ranges had. totally displaced previously used metal strain gage technology in. accelerometers. Free
  • Gun Hard Inertial Measurement Unit Based on MEMS Capacitive Accelerometer and Rate Sensor (.pdf)
    Smart munitions and missiles are increasingly incorporating inertial measurement units for guidance of short range weapon systems. In addition to usual high performance of the required sensors, namely, accelerometers and gyros, this application requires high shock survivability and post shock
  • Dual Die Compensation for MEMS Pressure Sensors
    Several pressure sensor manufactures promote product incorporating "dual die compensation." This compensation technique is employed for very low pressure sensors where common mode errors cannot be compensated by any other means for either gage or differential pressure measurements. There are two
  • How High in Frequency Are Accelerometer Measurements Meaningful
    of the. accelerometers when they are subjected to pyroshock [1]. In order. to support the development of a series of more robust MEMS. accelerometers, this paper answers the question: How high in. frequency response are accelerometer measurements meaningful?
  • Using Two Tri-Axis Accelerometers for Rotational Measurements (.pdf)
    that contains two or more accelerometers. With some understanding of fundamental physics, they can extract more than just linear acceleration data from their system. This application note describes how to use two Kionix MEMS low-g accelerometers to enable rotational measurements. Applicable theory, plots
  • Noise Measurements (.pdf)
    This technical note is intended to provide general guidelines for characterizing noise performance of MEMS accelerometers.
