Abstract: The present disclosure is directed to transparent, flexible substrates and, in particular, moisture-absorbing substrates for use in wound healing and wearable bioelectronics. Substrates of the present application can be formulated and used as wound dressings, electrodes, and electroceutical devices. Advantageously, in some aspects, substrates of the present application can absorb moisture (e.g., wound exudate, apocrine sweat, eccrine sweat), without swelling while also remaining transparent even with moisture absorption. In other aspects, substrates of the present application can be formulated to exhibit superior mechanical and electrical properties for application to a wide array of bioelectronic applications.

Abstract: An electrode can comprise carbon black and one of polydimethylsiloxane (PDMS) or PVA, wherein the carbon black has a weight of between 10% and 50% of a weight of the PDMS or PVA. The electrode can be suitable for bioelectronics. A pattern of hydrogel can be deposited on the electrode for providing adhesion to a subject. The electrode can be used in wound treatment and/or monitoring devices or in various other bioelectronics applications.
