LDT0-028K

LDT0-028K is a LDT with crimps vibration sensor/switch. It is a flexible component comprising a 28μm thick piezoelectric PVDF polymer film with screen-printed silver ink electrodes, laminated to a 0.125mm polyester substrate, and fitted with two crimped contacts. As the piezo film is displaced from the mechanical neutral axis, bending creates very high strain within the piezopolymer, and high voltages are generated. When the assembly 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 inertia of the clamped/free beam creating bending stress), the device will behave as an accelerometer or vibration sensor. Typical applications include vibration sensing in washing machines, low-power wakeup switch, low-cost vibration sensing, car alarms, body movement, and security systems.
