Stretchable Microfiber Sensors

We develop Soft Tubular Electronic Microfluidic (STEM) Sensors for applications in healthcare, VR and gaming. Specifically, we offer STEM sensors that possess distinct sensing modalities based on resistive, capacitive and enzymatic principles. The resistive and capacitive STEM sensors are flexible, stretchable, and sensitive to mechanical stimuli, enabling unobtrusive monitoring of pressure and strain when mounted on the body or weaved into textiles. The enzymatic STEM sensor provides a self-powered biochemical sensing solution to selective detection of vital physiological molecules. Beyond sensing technologies, the soft tubular microfluidics possesses huge potential in many other fields including fluid manipulation, drug delivery, microparticle and cell sorting, and engineering of blood micro-vessels.
