Sensor Array for Biomarker Degradation Measurement

Case ID:

This invention is an electronic sensor that is modified with a recognition element. This element is modified so it may be used to capture specific molecules from non-invasive biological fluids. These fluids include sweat, saliva, and tears. These biomarkers will react to enzymes which can be used in new products to provide quantitative information related to health and well-being of patients.

Wearable biochemical sensors are increasing in use due to their ability to personalize medicine and continuously monitor human health. Therefore, significant research and funding has been put towards developing sensors that enable real-time and non-invasive structure that are able to receive and measure various chemical constitutes in the human body. These include sweat, saliva, and tears. What has assisted increased investigation and funding towards wearable biochemical sensors has been the advances in material science and mechanical engineering. These complementary advances have assisted with providing various biomarkers.

Collection of sweat, a biofluid, is of extreme interest due to easy, non-invasive collection and rich content of important biomarkers. These include electrolytes, small molecules, and proteins. Establishing sweat monitoring techniques using simple fabric switching are limited to basic analysis in a controlled laboratory or hospital setting. Therefore, there is a need to develop a wearable device that can collect sweat, as a biological fluid and biomarker, so it may react with an enzyme to further understand patient health and well-being.
