Figure 4. Application demonstration of the strain-sensing glove in gesture monitoring and human-machine interaction. (A) Optical
image of the left hand wearing a strain-sensing glove. Scale bar: 20 mm; (B) The normalized resistance of the strain-sensing glove
changes as the left hand performs different gestures; (C) Schematic diagram of the human-machine interaction circuit using the strain-
sensing glove as a soft controller to manipulate the machine hand; (D) The left hand, wearing a strain-sensing glove, manipulates the
machine hand to perform mirrored motions. Scale bar: 50 mm.

wearing the strain-sensing glove made different gestures, the corresponding strain changes can be reflected
