"Wireless Human-inspired Bioelectronic Network"

Abstract:
60% of Americans live with at least one chronic disease. These diseases and associated comorbidities are now the leading causes of death in the United States. Effective management of complex chronic diseases requires body-wide, long-term, accurate, and continuous monitoring of multiple physiological signals to precisely determine the pathological state. These physiological signal monitoring can dramatically reduce the demand of physician visiting and increase patients’ engagement and treatment adherence rate. The ultimate technology platform for such kind of monitoring would be a close-looped wireless bioelectronic network. In this talk, I will discuss my previous research efforts on building such wireless bioelectronic network. First, I will describe a body area sensor network technology that utilizes novel wireless hybridization strategy to integrate soft on-skin devices with rigid high-performance silicon electronics to bypass the mechanical modulus mismatch. Then I introduced complex stretchable circuits so multiple analog sensors can be integrated into one soft skin sensing stickers. Next, I will introduce a smart bandage that can accelerate and monitor the wound healing process. Finally, I will switch the topic to triboelectric nanogenerator, an emerging technology for mechanical energy harvesting, to provide alternative power supply for the on-body network. Overall, the bioelectronic network technology platform could assess multiple health outcomes and treatment response to various chronic diseases. Ultimately, this technology will help to reduce chronic disease burden, lower medical costs and provide a better quality of life for patients.
