Projektbeschreibung
Neue Sensoren überwachen Herz-Kreislauf-Erkrankungen
Herz-Kreislauf-Erkrankungen sind weltweit die Todesursache Nummer eins. Innovative Prävention, Überwachung und Behandlung sind deshalb von höchster Wichtigkeit. In jüngster Zeit standen Überwachungslösungen wie etwa Biosignalsensoren im Mittelpunkt, um Anzeichen von Herz-Kreislauf-Erkrankungen früher erkennen und eine Behandlung früher einleiten zu können. Leider sind die heute verfügbaren Biosignalsensoren zu groß, zu auffällig und zu kostspielig, um weitverbreitet zum Einsatz zu kommen. Das EU-finanzierte Projekt UNOPIEZO wird dieses Problem angehen, indem ultradünne piezoelektrische Biosignalsensoren auf Polymerbasis entwickelt werden. Die Sensoren werden mit Technologien zur Fertigung gedruckter Elektronik hergestellt. Diese Sensoren werden unauffällig, energie- und kosteneffizient, sicherer für die Umwelt und gleichzeitig auch noch genauer sein.
Ziel
Goal: The goal of this project is to develop unobtrusive, affordable and accurate piezoelectric sensors for non-invasive biosignal monitoring.
Background: Continuous large-scale health monitoring of risk population carries significant benefits to the society, but is hindered by the lack of unobtrusive, affordable and accurate biosignal sensors. As an example, continuous monitoring of radial arterial pulse wave (PW) signal could enable early detection of cardiovascular diseases (CVDs, most common cause of death) and lead to significant reductions in societal costs associated with their treatment and current screening methods, both of which require hospital visits. Ultra-thin (t < 10 µm) sensors have been recently proposed to enhance the user comfort by recording the PW-signal non-invasively from the skin deformation caused by the pulsating radial/carotid artery located directly underneath the skin. Although the proposed devices have high potential for continuous PW-monitoring due to their unobtrusiveness, they suffer from drawbacks such as high energy consumption, costly fabrication, biocompatibility issues and/or low sensitivity.
Proposal: In order to meet the requirements of unobtrusiveness, affordability and accuracy, it is proposed that such biosignal sensors should be fabricated of piezoelectric polymer P(VDF-TrFE) using printed electronics fabrication technologies. The optical transparency and biocompatibility of P(VDF-TrFE) coupled with ultra-thin form factor of the device should result in sensors that are highly unobtrusive for the user. Furthermore, the ultra-thin form factor coupled with novel charge collector structure should maximize the sensor sensitivity, thereby increasing the accuracy of the biosignal measurement beyond the capabilities of conventional sensor structures. The sensor fabrication with additive and scalable printed electronics fabrication technologies should result in devices that are affordable for the user and for the environment.
