Abstract
A three-dimensional folding self-driving flexible respiration monitoring sensor and the preparing method thereof is disclosed. In the present invention a first friction unit and a second friction unit are set on a bottom of the box, which comprise a substrate, a conductive electrode layer and a friction layer respectively; the second friction unit is fixed on the bottom of the box; a friction layer of the first friction unit faces a friction layer of the second friction unit; a back plate is set on a substrate of the first friction unit; a balloon is between the box and the back plate; an inlet tube connects the balloon and the box, which is on a side wall of the box; the conductive electrode layer of the first friction layer and the second friction layer are connected to the electrometer respectively. Micro-energy of the respiration is adopted to monitor the breathing.
