The ferroelectric polymer P(VDF-TrFE) and its integration in flexible and stretchable electronics With the advent of the Internet of Everything (IoE) era, our civilization and future generations will employ an unimaginable complex array of electronics and sensors in daily life. There is thus a requirement for low-cost, flexible, and preferentially sustainable sensors to be integrated in the surface of everyday objects. Screen-printing is one of the most common techniques used in printed electronics for the fabrication of large-area flexible components and multifunctional devices. The printable ferroelectric polymer P(VDF-TrFE) is a multi-talent in future sensing applications. Based on the piezo- and pyroelectric effect the sensing of pressure, impact and vibration as well as IR radiation and proximity of human beings is feasible. The talk will cover the fundamental properties of the ferroelectric polymer, the sensor fabrication based on printing, as well as their applications in human-machine interfaces (HMIs), wearable devices, condition monitoring (CM), and energy harvesting. |
