About UHF RFID Battery-Free & Wireless Strain Gauges

  • RFID strain gauge sensors need no wires or batteries = no maintenance and long life.
  • Can be read through materials that typically cover structural components, with read range up to several meters on a metal-mount sensor – ideal for smart bridge applications and Structural Health Monitoring.
  • Strain resolution better than 15 u-strain using a standard +/-1000 u-strain sensor.
  • Sensors can be installed & calibrated on-site.
  • Use on-board temperature sensor for strain gauge temperature compensation, if needed.
  • Data-logging capability – track and compare for predictive maintenance.
  • Each wireless strain gauge sensor has a unique ID# so that many sensors can be read by one reader at the same time.
  • Patents pending.
  • Quickly & easily monitor with a standard RFID reader – standard RFID protocol.

  • Active (battery-powered) strain gauges (strain gages) transmit hundreds of feet. Ultra-long-life batteries make them Practically Battery Free™.
  • Battery-Assisted strain data loggers store strain readings over time. Communication with the sensor is done with an RFID reader.
  • Energy harvesting strain sensors using solar cells provide long-range sensor transmissions with no battery to maintain.
