Development of Screen-Printed Flexible Sensing Systems for Biomedical Applications

Significant progress has been made recently in the field of flexible electronics. Flexible electronics offer many advantages over traditional rigid systems in biomedical applications, such as light weight and conformality, which expands the device design space and allows for deployment of electronics in new use cases. Meanwhile, the ancient technique of screen printing presents a simple, yet precise method of creating thin conductive films over large areas. This proposal aims to take advantage of these unique properties by applying screen printing techniques to the creation of new flexible electronic devices. The proposed work targets two main areas: wearable health monitoring and cell therapy manufacturing. In Aim 1, a high-density piezoresistive sensor array, capable of continuous monitoring of plantar pressure distribution, is integrated into a wireless smart insole system using screen printing. For Aim 2, screen printing enables the development of another multi-sensor array to detect contamination in bioreactors during cell therapy amplification. Finally, Aim 3 seeks to build upon the bioreactor sensor system by expanding the sensor’s targeting capabilities and improving the wireless long-term monitoring functionality. In combination, this research plan aims to leverage the characteristics of screen printing to advance the field of flexible electronics and enable the deployment of new sensing systems for the benefit of a diverse range of patients.
