Embodiment 1

[0035] Example 1 Preparation of triboelectric nano-electric sensing imaging fabric

[0036] Fabrication of highly electrophilic triboelectric fiber electrodes

[0037] Clean the copper wire, dry it naturally, and place it on the surface of the heating table for sintering. Disperse the polytetrafluoroethylene concentrate in ethanol and shake well to obtain a uniformly dispersed suspension. The obtained suspension was sprayed on a single copper wire with a diameter of 0.1 mm to obtain a conductive fiber coated with polytetrafluoroethylene (coating thickness: 0.05 μm). Put the obtained conductive fiber in an oven and heat it for 30 minutes, then take it out, and then you can get the conductive fiber whose surface is wrapped with nano polytetrafluoroethylene film.

[0038] A copper wire with a diameter of 0.1 mm is selected as the low electrophilic triboelectric fiber electrode, and the aspect ratio is greater than 10:1.

[0043] Fabrication of highly electrophilic triboelectric fiber electrodes

[0044] Clean the silver wire, dry it naturally, and place it on the surface of the heating table for sintering. Disperse the polyvinyl chloride concentrate in acetone and shake well to obtain a uniformly dispersed suspension. The resulting suspension was spin-coated on a single silver wire with a diameter of 0.05 mm to obtain a conductive fiber coated with polyvinyl chloride (coating thickness 20 μm) on the surface. Put the obtained conductive fiber in an oven and heat it for 50 minutes, then take it out, and then you can get the conductive fiber coated with nano polyvinyl chloride film on the surface.

[0050] Fabrication of highly electrophilic triboelectric fiber electrodes

[0051] Clean the titanium wire, dry it naturally, and place it on the surface of the heating table for sintering. Disperse the polydimethylsiloxane concentrate in ethanol, shake well to obtain a uniformly dispersed suspension. The obtained suspension was sprayed on a single titanium wire with a diameter of 0.2 mm to obtain a conductive fiber coated with polydimethylsiloxane on the surface (the thickness of the coating was 0.10 μm). Put the obtained conductive fiber in an oven and heat it for 60 minutes, then take it out, and then you can get the conductive fiber coated with nano polydimethylsiloxane film on the surface.

Abstract

The invention provides a friction nanometer power generation sensor array with a fabric structure. The friction nanometer power generation sensor array is characterized in that the fiber electrode isformed by weaving insulating space lines, low electrophilic friction power generation fiber electrodes, high electrophilic friction power generation fiber electrodes and other non-conductive fibers ina warp-weft staggered mode, one high electrophilic friction power generation fiber electrode and two insulating space lines form a group of fiber groups, the high electrophilic friction power generation fiber electrode is located between the two insulating space lines, and the diameter of each insulating space line is larger than that of each high electrophilic friction power generation fiber electrode; the other non-conductive fibers and the low electrophilic friction power generation fiber electrodes are distributed at intervals in one direction, and the fiber groups and the other non-conductive fibers are distributed at intervals in the other direction; in the weaving process, the interface pressure of a single warp and a weft is 0.5kPa-5MPa, and the tension range of the single warp is10(-3)N-10N. The pressure shape and size can be sensed, and the friction nanometer power generation sensor array can be suitable for any working plane, and is light, flexible and wearable.

Description

technical field [0001] The invention relates to a triboelectric nanometer power generation sensor array, in particular to a friction nanometer power generation sensor array with a fabric structure. Background technique [0002] Today, with the rapid development of electronic products and electronic technology, wearable flexible electronic technology has become the current development trend; more and more flexible electronic devices have been used in energy storage and conversion, pressure sensing and portable devices. Among them, pressure sensors have a wide range of potential applications in the fields of human-computer interaction, human motion perception, health monitoring, intelligent robots, and electronic skin. For example, the existing intelligent robots have certain thinking, decision-making, language communication and operation functions, etc.; but there is still a great lack in tactile sensing; and other fields have brought about huge innovations. Traditional pre...
