Unobtrusive printed piezoelectric sensors for non-invasive biosignal monitoring

Description du projet

De nouveaux capteurs pour la surveillance des maladies cardiovasculaires

Les maladies cardiovasculaires constituent la principale cause de décès dans le monde. Il est crucial de développer des innovations visant à les prévenir, à les surveiller et à les traiter. Plus récemment, la recherche a mis l’accent sur des solutions de surveillance telles que des capteurs de biosignaux permettant de détecter et de prendre en charge plus rapidement les maladies cardiovasculaires. Malheureusement, les capteurs de biosignaux actuels sont trop imposants, trop envahissants et trop onéreux pour permettre leur généralisation. Le projet UNOPIEZO, financé par l’UE, répondra à ce problème en mettant au point des capteurs de biosignaux ultra-fins en polymère piézoélectrique. Ces capteurs emploieront des technologies de fabrication électronique imprimée. Ils seront peu envahissants, efficaces d’un point de vue énergétique, rentables et plus sûrs pour l’environnement, tout en étant plus précis.

Objectif

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.
