Piezofilm FDT Series

Image FDT

The “F” in FDT Series stands for “‘Flexible Leads”. These are rectangle elements of Piezo film with silver ink screen printed electrodes.

Rather than making the lead attachment near the sensor, the Piezo polymer tail extends from the active sensor area as flex circuit material with offset traces.

This gives a very flat, flexible lead with a connector at the end. The FDT elements are available in a variety of different sizes and thicknesses.

They are available without a laminate (FDT), with a laminated (0.005” mylar) on ones side (FLDT) or with tape release layer adhesive (FDT with adh) in the sensor area.


  • Thin piezo film sensor
  • Flexible leads give flat profile to the sensor
  • Dynamic strain sensing with a high output
  • Typical interface to a 1 or 10MΩ input impedance
  • Output voltage dependant on force applied 10mV to 100V


  • Sensing Direct Contact Force
  • Recording Time of an Event
  • Counting Number of Impact Events
  • Measuring Impact Related Events
  • Sensing Vibration using Cantilevered Beam
  • Wakeup Switch
  • Motion Detection
