Moving Electrochemical Sensing from the Lab to Flexible Platforms
There is a strong need to manufacture and deploy flexible, wearable sensors for continuous monitoring of both biomarkers indicative of human performance, as well as environmental factors that may impact performance. However, the current form-factors and cost of these devices are problematic for many scenarios and limit their wide-scale use. Here we present two examples of moving towards flexible integrated electrochemical sensors for both environmental and physiological monitoring: 1) Integration of our novel isopropyl alcohol sensor on a miniaturized MEMS chip with the flexible Arduino for real-time measurement of isopropyl alcohol. 2) Demonstration of the first fully-printed, flexible 3-electrode aptasensor for detection of proteins and protein biomarkers. The latter sensor has the added benefit of being generated using roll-to-roll compatible processes and solvent resistant. Future work will continue to expand the range of sensors that can be readily integrated into these flexible platforms, as well as a demonstration in environments that simulate deployment in real-world conditions.
