Soft Bioelectronics Systems

     With the knowledge we learned and created in mechanics, materials, manufacture and bio-e interface, my group has built a few soft bioelectronic systems on our own (k-m)15,16,26 and in collaboration (e.g., n).24,25,27,28,29, Specifically, the modular wireless e-tattoo made through the “cut-solder-paste” method could be disassembled and reconfigured into e-tattoos of different sensing modalities because they all share a generic NFC layer (k). We also had a cover article on Adv. Sci. reporting a dual-mode e-tattoo that could simultaneously measure one’s electrocardiogram (ECG) and seismocardiogram (SCG), out of which cardiac time intervals and ultimately one’s blood pressure could be extracted beat-by-beat (l).26 The SCG sensing was achieved through am ultrathin stretchable sensor made out of piezoelectric polyvinylidene fluoride (PVDF) which was designed based on our mechanics knowledge of piezoelectric serpentines.30
