Product Description
Piezoelectric PVDF Sensors with leads. Made with PolyK piezo PVDF film with high d31.
Active film thickness 110 um. Capacitance is about 0.1 nF/cm^2, Young's modulus 2500 MPa, piezo d33 > 28 pC/N and d31 > 28 pC/N.
Very narrow strip and fiber with thickness of 110 um and two surfaces with Copper electrode (about 80 nm).
Width of 1 mm, 2 mm, 3 mm, or others.
Standard length is 250 mm (capacitance about 0.5 nF for 2 mm x 250 mm), each pack have four sensors.
Used for elongation sensor (heart rate, breath, music), smart fiber, smart textiles, large area low cost sensors...
Youtube video as sensor (or energy harvesting, mechanical force pressure --> electrical signal):
As smart textile speaker:
Can be laminated to any surface with double side tape
Electrode can be thin copper or aluminum.
Other sensor width and length can be produced upon request.
A. with pin connector (solderable)
B. with 100 mm long soldered wires
Thin wire can also be attached with silver epoxy.
Note: the effective area (capacitance) can be changed by simply cutting it with scissors to make it smaller. After cutting, please use IPA or acetone to clean the cutting edges and make sure there is no electrical short circuit between top and bottom electrode.
