a Schematic illustration of the EES, including the epidermal sensing module, the soft DAQ module, and the user interface. b Wireless DAQ module laminated on the arm. Scale bar, 10 mm. c System-level workflow diagram of the EES, showing analog signal acquisition, procession, wireless transmission, compensation algorithm paths from sensor array to the customized user interface (numbers in parentheses indicate the corresponding labeled components in (a). d The photograph of a participant wearing the epidermal sensors. Scale bar, 50 mm. e Optical and microscopic images of filamentary epidermal sensors wrapped around a hair strand. The scale bars on the left and right panel are 1 cm and 30 μm, respectively. f Components and interconnections of the EES.
