What is PyzoFlex®?
PyzoFlex® is a fully printed sensor technology based on a printable polymer ink. The transducer is manufactured using a screen printing process, which enables printing of customized sensors of specific shape and size on a variety of substrates including plastic film, paper, glass and metal. We are able to comply to customers’ needs at a low cost. Our ferroelectric sensor ink allows a 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 transducers themselves do not require a power supply and in fact can also be used for energy harvesting.
PyzoFlex® technology consists of:
(i) Transducer: Know-how and patents regarding the production and processing of polymer- or nanocomposite inks as well as the printing of these inks on various materials and thus the production of components with functional layers and structures
(ii) Sensor-specific electronics: Know-how for data processing and communication of sensor signals
(iii) Software: Customer or application-specific interpretation of sensor signals, thus resulting in devices for different applications in IoT, consumer electronics, security, industry 4.0, automotive, smart textiles, smart living and life science, sport and many more.
Even the smallest changes in pressure, temperature or vibration generate charges in the sensor layer. These charges migrate to the sensor-electrodes and are read out as voltage/current signals using application-specific electronics. The signal level is proportional to the intensity of the respective stimulus, thus allowing not only detection of the location of contact, but also its intensity.
PyzoFlex® is an affordable, printable (by e.g. screen printing) sensor technology that can be implemented on an industrial scale. It allows the large-scale and accurate measurement of temperature and pressure changes as well as vibration monitoring in objects and their environment. In addition, there is know-how for the data processing and communication of the sensor signals (sensor-specific electronics) as well as customer or application-specific interpretation of the sensor signals (software or intelligence), thus resulting in devices for different applications Wherever pressure / temperature changes, vibrations or shock waves occur, piezoelectric and pyroelectric generators can be used to convert mechanical deformation (changes in thickness) and temperature differences into electrical energy. Ferroelectric polymers belonging to the PVDF-Class (polyvinylidene fluoride) are used as a basic material due to the fact that they exhibit strong piezoelectric and pyroelectric activity after a poling procedure. These materials are also extremely stable, UV and weather resistant, flame-retardant and have a high chemical durability. Any mechanical deformation caused by contact, pressure or movement can also be used to generate electrical energy (piezoelectric energy harvesting).
These sensors can easily be implemented or laminated in/onto different surfaces giving them an added value. The unique properties and robustness of this technology open up a host of entirely new possibilities and make it suitable for many different fields of application – as there are: IoT, smart living and smart city, automotive & smart mobility, smart wearables, cyber physical systems, strain gauges, and many more.
