Piezo element sensor skin#
Their small size and high sensitivity make them well suited to the above applications.īecause they are so adaptable, piezoelectric sensors are a popular choice for applications in the medical industry and they are often used for pulse measurement - for this they can be bonded to the patient's skin and are sensitive enough to monitor the pulse. Some more commonplace applications where they are used are Piezoelectric sensors are used in a variety of applications through different industries as they are so diverse. Piezoelectric sensors have the following characteristics They will often be moulded or glued into place within applications. Piezoelectric sensors are strong, lightweight and constructed of flexible plastic enabling them to be available in a range of sizes, shapes and thicknesses. Piezo sensors are part of our product range here at Variohm we can offer piezo cables, film elements, piezo film sheets and piezo switches. They are highly sensitive and very small in size making them well suited to everyday objects. “Piezo” is Greek for “press” or “squeeze” so a piezoelectric sensor effectively measures compression using the piezoelectric effect.Ī piezoelectric sensor converts physical parameters - for example, acceleration, strain or pressure into an electrical charge which can then be measured. The use of them is growing significantly throughout different industries and they are sometimes incorporated into other sensors. This makes them a popular choice for many applications.
A Piezoelectric Sensor requires no external voltage or current source, they are able to generate an output signal from the strain applied.
