Phys.org May 25, 2024 The current understanding of electric double layer (EDL) charging is limited to simple geometries. An international team of researchers (USA – University of Colorado, Poland) introduced a model to predict electrolyte transport in complex networks of slender pores. Their methodology accurately captures the spatial and temporal dependencies of charge density and electric potential, matching results obtained from computationally intensive direct numerical simulations. Their network model provided results up to six orders of magnitude faster. They used the framework to study the impact of pore connectivity and polydispersity on electrode charging dynamics for pore networks and discussed […]

MIT engineers develop a soft, printable, metal-free electrode
MIT News June 15, 2023 Conducting polymer hydrogels have emerged as a promising candidate for bioelectronic interfacing with biological systems. Despite the recent advances, the development of hydrogels with both excellent electrical and mechanical properties in physiological environments is still challenging. An international team of researchers led by MIT has developed a bi-continuous conducting polymer hydrogel that simultaneously achieves high electrical conductivity, stretchability, and fracture toughness in physiological environments. It is readily applicable to advanced fabrication methods including 3D printing. Enabled by these properties, they demonstrated multi-material 3D printing of monolithic all-hydrogel bioelectronic interfaces for long-term electrophysiological recording and stimulation […]
