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 one
side (FLDT) or with tape release layer adhesive (FDT with
adh) in the sensor area.
Features:
· 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 10 M Ω input impedance
· Output Voltage (dependent on force applied) 10 mV to 100V
Applications:
· 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
