Rapid evaluation of physiological conditions offers huge advantages to personnel in areas such as emergency medical response and professional sports, and would allow continuous monitoring of physiological health, as well as possibilities for immediate treatment of serious injuries. High fidelity real-time diagnostics allowing simultaneous detection and comparison of several biological markers would allow profiling of an athlete’s health during training to avoid any excess force on their physiology. It could also provide medical personnel with a more direct treatment path to enhance survival rate of patients.
Bio-sensing in human perspiration can provide a non-invasive pathway to such diagnostics. For example, continuous monitoring of sweat lactate during exercise can benefit health and fitness applications of an athlete or patient. In this abstract, we outline wearable chemical sensors that utilize the expertise and access to high performance tools at NovaCentrix.
NovaCentrix inks capitalize on advanced materials and formulation expertise to provide a variety of options for specific applications, as well as the ability to tune factors such as conductivity, stretchability and solderability, towards a variety of printing techniques. These capabilities allow us to develop suitable materials towards electrochemical sensors that will conform to the physical and chemical requirements outlined in previous paragraphs. Add to this, the design of our inks specifically for use with low-temperature substrates including paper and plastics so that the convenience of a disposable biosensors can fully be realized. Solderability can be a significant advantage in the ease of combining a sensor to a reader. At NovaCentrix, inks have been developed to couple this feature with stretchability and bendability in order to address the physical demands of an on-body sensor.
Finally, the deployment of PulseForge, our photonic curing tool, allows us to thermally process inks over temperature sensitive substrates without damaging them. The use of such substrates significantly reduces the cost of each sensor thus rendering them available to a much wider (and lower budget) market.
