• Piezo Film Sensors (High Sensativity, AC Coupled, Laminated, Robust)
• The LDT0-028K is a flexible component comprising a 28 µm thick piezoelectric PVDF polymer film with screen-printed -ink electrodes, laminated to a 0.125 mm polyester substrate, and fitted with two crimped contacts. As the piezo film is displaced from the mechanical neutral , bending creates very high strain within the piezopolymer and therefore high voltages are generated.
• When the assembly dimensions is deflected by direct contact, the device acts as a flexible "switch", and the generated output is sufficient to trigger MOSFET or CMOS stages directly. If the assembly is supported by its contacts and left to vibrate "in free space" (with the inertia of the clamped/free beam creating bending stress), the device behave as an accelerometer or vibration sensor.
• Adding mass, or altering the free length of the by clamping, can change the resonant frequency and sensitivity of the sensor to suit specific applications. Multi- response can be achieved by positioning off center.
• The LDTM-028K is a vibration sensor where the sensing comprises a cantilever beam loaded by an additional mass to offer high sensitivity at low frequencies.
