The present invention is directed to the production of stretchable wrinkled film electrodes for use in wearable/portable ROC systems using electrochemical analysis techniques. A polymer layer is disposed on a conductive substrate and a sacrificial layer is disposed on said polymer layer. An electrode shape template is cut out of adhesive and disposed on the sacrificial layer. A metallic film is disposed on the sacrificial layer by the electrode shape template. The disposed layers are removed from the conductive substrate and placed in an oven to allow said layers to shrink. The shrunken metallic film is treated with a solution to promote bonding between the film and an elastomer. The elastomer is drop-cast onto the shrunken film and the sacrificial layer is dissolved to detach the shrunken polymer layer. The shrunken film and elastomer are placed in a chemical bath and dried, producing the stretchable wrinkled film electrode.

Support device for supporting at least one body part of a user at least in portions, optionally completely, comprising a support body, which comprises at least one support region for supporting at least one body part of a user at least in portions, optionally completely.

Collection devices, systems, and methods include those for collecting volatile organic compounds (VOCs) and/or other chemical substances from a target area of a subject’s anatomy (e.g., a subject’s skin, a wound on a subject, etc.). In some cases, the collector may have a collection component including an adsorbent material. The collector may be used with a pump. The pump may be configured to draw a fluid flow containing one or more chemical substances from a target area on a subject’s anatomy through the collection component. The collection component may be configured to collect at least some of the chemical substances from the fluid flow as the flow passes through the collection component.
