From: An epidermal sEMG tattoo-like patch as a new human–machine interface for patients with loss of voice
a Schematic drawing showing the control flow of the human–machine interface based on the epidermal sEMG tattoo-like patch for patient voice loss. b Layer-by-layer configuration of the epidermal sEMG electrode patch. c Epidermal sEMG tattoo-like patch mounted on the forearm. The configuration and the internal structure of the epidermal sEMG electrode, including two sensing electrodes (MEA) and a reference electrode (REF) of filamentary serpentine (FS) meshes, are shown. d Double-transfer process of the epidermal sEMG electrode from the wafer to the sterile wound dressing.
