Arkema Piezotech polymers are 2 range of electroactive polymers. Piezotech FC: P(VDF-TrFE) copolymers, which are piezoelectric, pyroelectric, and ferroelectric and often be used for sensor, energy harvesting, speaker; Piezotech RT, P(VDF-TrFE-CTFE) and P(VDF-TrFE-CFE) terpolymers with remarkable high-k, electrostrictive, and electrocaloric properties, which be applied in OTFT, actuators and electrocaloric devices. these polymers are fine, lightweight and flexible, and can be integrated using simple process. In this presentation, we will firstly use some graphic to demonstrate the mechanism of the Piezo effect, how & what happen at the molecular level. then we will show different applications with videos of sensors, actuators made by Piezotech material that turn surfaces, objects and buildings into smart systems.
1. printed pressure/vibration sensor integrated into insole & mattress to monitor for health, wellness and safety. comparing to force resistive sensor, Piezo material has better efficient (drift, sensor fatigue) and reliability. we will show short video of monitoring data, case study of smart sleep mattress, smart insole, pulse monitoring.
2. Sensor to be applied into sport equipment, such as golf club, tennis racket.
3. Electrostrictive effect of Piezotech® RT polymers, a guide wire for endovascular navigation in order to reach the target regions inside blood vessels and through the tortuously curved pathways of blood vasculature. Minimizing risks and complications of the procedure by improving steerability performance. Decrease the probability of infection;
4. Acoustic monitoring sensor for H2 tank structural health monitoring. Record and localize acoustic waves resulting from mechanical modifications of the composite using piezo-active polymers. Increasing the security of tanks by fatigue/impact identification and realizing the requalification of the tank in real time (life time prediction). such application could be on applied to monitor the status of the wind turbine blade to allow remote management, optimize maintenance and extend lifetime;
5. Haptic glove which is glove with haptic module made by PIEZO terpolymer
