a Image of the LCD wristwatch and the ECD for the Na+ potentiometric sensor. Scale bar, 1 cm. b Images of the LCD screen with different input voltages. c The display of the ECD with different sensor voltage input. d The photo image of the all-printed flexible potentiometric sensor (top) and the calibration curve of the Na+ sensor (bottom). Scale bar, 2 mm. e-f Voltage vs. time curves of the wearable microgrid system powering the Na+ sensor-ECD system in pulsed mode during a 10-min running session followed by 20 min of rest, with only the BFC module operating, only the TEG module operating, and both harvesters operating together (e); and the LCD wristwatch continuously during a 7-min running session followed by 23 min of rest (f).
