Novel, self adhesive PDMS mesh inspired by the skin ECM for skin contact applications
About
Inspired by the dermal extracellular matrix, Dr. Ahyeon Koh has developed a three‐ dimensional, ultrathin, and fibrous polydimethylsiloxane (PDMS) membrane engineered for adhesion to skin and chronic continuous monitoring applications. The elastic PDMS mesh has a minimal mechanical footprint, with elasticity and durability comparable to skin tissue. The self-adhesive platform exhibits biomimetic viscoelastic and nonlinear mechanics, cytocompatibility, and a bio‐fluid permeable interface for transdermal water, gas, and small molecule diffusion for stretchable bioelectronics.
Key Benefits
Biomimetric: inspired by the skin extracellular matrix with mechanic characteristics comparable to the epidermis. Permeable: demonstrated diffusion of various small molecules, gases, and transdermal water. Biocompatible: keratinocyte viability on the PDMS mesh for up to 7 days. Self-adhesive: durable bonding mechanism mitigating the need for adhesive
Applications
Wound care, Bio-integrated wearable electronics for monitoring: Various biomarkers, Athletic performance, Vital signs, Health status
