Here, an alternative to the existing devices, which mainly are made of laser-perforated thin membranes, is presented using polydimethylsiloxane (PDMS) and soft lithography. The proposed method overcomes the fabrication challenges of replicating the eccrine sweat gland structure. Sweat glands conduits are faithfully defined in-plane and the skin interface is created by bonding multiple PDMS layers. Parameters such as sweat duct diameter, sweat gland density and wettability properties were successfully replicated Postprint (published version) Àrees temàtiques de la UPC::Enginyeria mecànica::Mecànica de fluids Skin Perspiration Sweat glands Microfluidics Skin phantom Perspiration Sweat Artificial skin In vitro testing Wearables Pell Perspiració Glàndules sudorípares Microfluídica 3D skin microfluidic phantom for in vitro wearable testing
