a Illustration of the diamond-patterned electrodes in a transparent and stretchable touch sensor. The scale bar length is 400 μm. b Capacitance change depending on the distance of the finger from the sensor surface. c Capacitance changes depending on the strain. d Capacitance changes depending on the bending radius. e Positioning sites for EOG, ECG, and EMG sensors: black for EOG, red for ECG, and blue for EMG. f Optical images of the mounted EMG sensor and microscopic view of the sensor electrode patterns. g–i Plots of typical waveforms (left) and measured signals (right) from g EOG, h ECG, i EMG sensors.
