US MEAS Piezoelectric Film Sensor - Coaxial Piezoelectric Cable

1. US MEAS Piezoelectric Film Sensor Coaxial Piezoelectric Cable Description:

Piezoelectric cable is another form of piezoelectric film sensor, featuring a coaxial design with insulating materials between layers. When the piezoelectric cable is compressed or stretched, the piezoelectric effect occurs, generating a charge or voltage signal proportional to the pressure. Piezoelectric cables offer many advantages in certain applications: due to the coaxial design, self-shielding can be achieved, making them suitable for high EMI environments; using standard coaxial bonding technology, they can be made into passive coaxial cables; due to their high strength, they can be used for axle counting on heavy trucks and trailers; as linear sensors, they can be applied to large-area monitoring.
We can provide two specifications of piezoelectric cables: copolymer and wrapped. For copolymer piezoelectric cables, a special material is directly extruded onto the wire and then polarized; for wrapped piezoelectric cables, PVDF film is double-helically wound around the central conductor. The copolymer raw material is quite expensive and only available in limited substrates.
