All-new piezoelectric sensor
Introducing the revolutionary new piezoelectric device from Sekisui.
Piezoelectric materials generate a minute but distinct electric voltage when subjected to pressure---this is called the piezoelectric effect.
Conventional piezoelectric elements are made from hard materials such as ceramic or crystal. But Sekisui has developed a revolutionary new ultrafine polyolefin piezoelectric foam material, which delivers superior piezoelectric sensitivity and can be used to make thinner and more flexible sensors.
The new Sekisui sensor consists of charged polyolefin foam on an aluminum backing sheet. When the sensor is subject to pressure, the change in shape (compression) generates a minute voltage that is transmitted to the aluminum sheet and converted into electrical signal.
The revolutionary new Sekisui sensor is thinner and more versatile than conventional sensors, with vastly improved sensitivity.
1. Improved sensitivity
The ultrafine polyolefin foam material, developed by Sekisui specifically for piezoelectric sensor applications, delivers an impressive 30 mV/N sensitivity for pulse measurement. Advanced circuit processing is used to separate out data for heart rate, breathing, snoring and body movement from signals generated by a sensor installed under a mattress, inside a car seat, or even attached to clothing.
2. Thin and flexible
The Sekisui piezoelectric sensor can be fabricated at thicknesses of as little as 700 µm. The flexible polyolefin foam allows far greater design freedom than conventional plastic sheeting. Sheet sizes range from small (2 cm × 2 cm) to large (100 cm × 100 cm), suitable for compact applications such as wearable computers through to large installations such as mattress sensors.
3. Versatile
Sekisui piezoelectric sensors are designed to operate under a wide range of ambient conditions, from very hot and humid (80°C, RH95%) to very cold (−20°C). The sensor material is rugged and durable, exhibiting no loss of performance when subjected to 500 repetitions of bending and external forces of up to 2 MPa. It also delivers excellent consistency of electrostatic performance over the long term, unlike other conventional polyolefin foams.
Potentially yields a whole new range of data.
Sekisui piezoelectric sensor sheeting is thin and flexible yet delivers excellent sensitivity performance, and is suitable for a wide range of applications. We believe that this highly versatile product opens up a whole new world of possibilities for sensing systems.
