Know-how and patents regarding the (i) production and processing of polymers (as polymer- or nanocomposite ink) as well as the printing of this ink on various materials (process) and thus the production of components with functional layers and structures (printed sensors). In addition, there is know-how (ii) for the data processing and communication of the sensor signals (sensor-specific electronics) as well as (iii) customer or application-specific interpretation of the sensor signals (software or intelligence), thus resulting in devices for different applications (IoT, consumer electronics, security, cyber physical systems, automotive, wearables, smart living and life science, sport), and many more.
PyzoFlex® means a fully printed sensor technology based on a printable, polymer ink. The transducer is fabricated via a screen printing process. Screen printing offers the ability to print customized sensors in terms of geometry and size and allows the printing on versatile substrates (plastic film, paper, glass, metal etc.) – thus addressing specific customer needs at low costs. The ferroelectric sensor ink allows the system to detect changes in temperature (∆T; pyroelectric), pressure (∆P; piezoelectric) as well as structure born sound (Hz; vibration). Due to the sensing principle of PyzoFlex®, the sensor itself does not need a power supply and can also be used for energy harvesting.
Smallest changes in pressure or temperature as well as vibration generate charges in the sensor layer which flow to the electrodes and can then be read out as voltage/current signals via application-specific electronics. The detected signal height is proportional to the strength or speed of the contact i.e. it is possible to detect not only where the contact is made, but also how strong and how fast.
