Prototyping & Lab-scale Evaluation
Piezotech produces samples of electroactive polymer-based films, screen-printed piezoelectric transducers and piezoelectric PVDF gauges. Each piezoelectric sample is individually and accurately poled using our unique poling process. Piezotech supplies high quality devices with reproducible and homogeneous polarization. Our process provides control of:
- Electromechanical performance
- Spontaneous polarization
- Remnant polarization
Electroactive Film Samples
Piezotech® has the capabilities to sputter 12*12 cm films of quality-controlled P(VDF-TrFE), and P(VDF-TrFE-CTFE) with Cr/Au, allowing for electrode coverage over the whole film surface.
| Base Polymer | Piezotech® FC20 | Piezotech® FC30 | Piezotech® RT-TS |
|---|---|---|---|
| Thickness (µm) | 10 or 20 | 10 or 20 | 10 or 20 |
| Poled | Available | Available | Not concerned |
| Metalized Cr/Au | Available | Available | Available |
Screen-printed Piezoelectric transducers
Piezotech® team is able support your screen-printing developments with dedicated R&D equipment. We offer samples of standardized screen-printed piezoelectric transducers, allowing ease of integration into prototypes.
PVDF Gauges
Piezotech® provides PVDF gauges with 1*1 mm or 5*5 mm active area. They are suitable for a wide range of sensing applications; e.g., detecting shock and/or pressure changes. Our unique process allows us to produce calibrated sensors with:
- High reproducibility
- Rapid response (nanoseconds)
- Large stress range (mPa to GPa)
- High Sensitivity
- Flexibility at minimal thicknesses
