1m long piezo sensor generates very strong signal
This is a 1 m long piezo PVDF film sensor made with 110 um thick PolyK Piezo PVDF film with screen printed silver electrode and water-proof coating. Effective width is 10 mm and total width is 14 mm. https://piezopvdf.com/Sensor-1-m-leng...
it can easily generate over 10 V output by hand-stretching.
It can have solderable pin connectors or rivet connectors with soft silicone wires.
For health monitoring (heart rate, breathing respiration, etc) around the chest, under bed,/pillow, It can also be used as energy harvesting device to convert mechanical energy to electricity.
As strong as Mylar polyester film, it is robust but truly flexible.
These piezo film sheets can be produced in very large size (master roll is 500 mm wide and over 100 m long) and can be used to produce large size sensors at relatively low cost.
When thin metal electrode is used, it can also be manufactured in roll-to-roll (such as sputtered copper, aluminum, etc) at low cost.
It can also be used in converting mechanical motion to electricity in large scale (such as ocean wave energy harvesting).
If you have customized piezo PVDF or PVDF-TrFE sensors that were produced by Measurement Specialty (MEAS) or TE Connectivity or Piezotech-Arkema, and they stopped the customized sensor business, please contact us sales at piezopvdf.com. We produce the piezo film and we have in-house sensor fabrication machines in the USA.
