The output of two systems is compared for a single unit, and according to this comparison, the array of compression type system has been designed. The compression type piezoelectric system is excited by the force applied by the train, and cantilever beam type system is excited by the ground vibrations of the track. The lead zirconate titanate (PZT), which is one of the recent piezoelectric, which accumulates more charge on mechanical disturbance, is used in both the cases. ![]() These systems are suggested to be embedded on the railway track and attached to the rail tracks to produce the electrical output. The two piezoelectric systems used for analysis are compression type piezoelectric system and cantilever beam type piezoelectric system. Take a look at the various piezoelectric products on our websiteįor more information on piezoelectric sensors or to discuss any of the products we can offer, please contact us.In this paper, an analysis of two methods of harvesting the electrical power from the two different piezoelectric systems in railway traction system is carried out. Various thicknesses and sizes available.Compatible for electrical to mechanical conversions.Have an operating temperature of -40☌ to +85☌.They are available in various forms film, cable and switches and in either standard or customised packages. Our Piezoelectric sensors come from our supplier TE. Non-destructive testing for various parts including parts for aerospace applications.Some other more industrial applications which use Piezoelectric sensors are They are used in stethoscopes, and ultrasound, to measure the effectiveness of anaesthesia, for various measurements during sleep studies and within pacemakers to detect the level of movement and activity of the patient. 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.
