Figure 9. (A) Two TATSAs integrated into a shirt for real-time monitoring of pulse and respiratory signals; (B) schematic illustration of the combination of TATSA and clothes; (C) TATSA with the front, right, and top sides of the knit loops, and schematic illustrations of charge transfer through a contact unit during the pressure application and release steps; (D) photographs of TATSAs stitched into a wristband, fingerstall, sock, and chest strap, and the related measured waveforms; and (E) TATSA placed on the chest for measuring respiration signals, and the detected voltage-time and its decomposition into the heartbeat and respiratory waveforms^[122]. TATSA: Triboelectric all-textile sensor array.
