| dc.title | Permeable and stretchable bioelectronic devices and systems using liquid metal | en_US |
| dcterms.abstract | Permeable stretchable electronics have emerged as a promising avenue for next-generation bio-integrated electronics due to their ability to enhance physiological comfort during long-term wear. However, existing technologies lack a universal fabrication method for incorporating permeable stretchable materials into a mass-producible way. Furthermore, highly stretchable 3D integrated circuits with complex functions and skin-like softness and permeability are yet to be achieved. | en_US |
| dcterms.abstract | This study presents a wafer-scale patternable strategy for the high-resolution fabrication of supersoft, stretchable, and permeable liquid metal microelectrodes (Plms) and their implantation as a neural interface for high spatiotemporal mapping and intervention of electrocorticography (ECoG) signals in living rats. In addition, a micropatterning technology of PlmHs on polyacrylic acid (PAA) hydrogels has been developed for permeable transparent bioelectronics. Finally, a permeable and 3D integrated electronic skin (WPE-skin) possessing skin-like softness and stretchability, outstanding permeability, and robust electronic integration capable of sensing, signal processing, analysis, intervention, and communication in a wireless manner has been proposed. The comprehensive studies open a new avenue to bridge soft and stretchable biology with electronic functions and integrations using LM. | en_US |
| dcterms.abstract | In summary, this work studied the feasibility of developing permeable stretchable LM-based bioelectronics consisting of materials, fabrications, devices, and systems. Various LM-based bioelectrodes, bioelectronic devices, and systems have been successfully demonstrated. Such comprehensive studies open a new avenue to bridge soft and stretchable biology with electronic functions and integrations using LM. In principle, these fabrication and integration strategies are expected to have significant impact in permeable bioelectronics are also versatile to other bioelectronic devices and systems. | en_US |
