![]() ![]() ![]() It also delivers excellent consistency of electrostatic performance over the long term, unlike other conventional polyolefin foams. They are the most sensitive strain gauge technologies offering stable and repeatable accurate electrical output. In the present work, PVDF-based nanocomposites loaded with BaTiO3 nanoparticles (NPs) of various weight fractions were prepared by the. 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. The piezoelectric pressure sensors of the S series offer measuring ranges (up to 1000 bar) and temperature ranges (up to 400C) in a small footprint. Piezoelectric sensors do not require any power to continuously monitor an environment. Poly(vinylidene fluoride) (PVDF)-based piezoelectric materials are promising candidates for sensors, transducers, and actuators, due to several distinctive characteristics such as good flexibility, easy processability, and high mechanical resistance. Sekisui piezoelectric sensors are designed to operate under a wide range of ambient conditions, from very hot and humid (80☌, RH95%) to very cold (−20☌). 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. The flexible polyolefin foam allows far greater design freedom than conventional plastic sheeting. The Sekisui piezoelectric sensor can be fabricated at thicknesses of as little as 700 µm. Gene Chen, VP of Engineering and Advanced Materials. 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. 'Our new piezo film sensors offer unique sensing capabilities due to their wide dynamic range and broad frequency band, while our advanced matrix sensor solutions allow us to offer custom configured matrix sensor arrays that are tailored to each customers unique requirements,' said Dr. The ultrafine polyolefin foam material, developed by Sekisui specifically for piezoelectric sensor applications, delivers an impressive 30 mV/N sensitivity for pulse measurement. ![]()
