▎ 摘  要

NOVELTY - The sensor has an organic insulating film whose two sides are adhered with a dual-sided conductive copper tape. Upper and lower electrode patterns of a graphene are arranged in a vertical manner. A substrate material completely covers a square hollow structure, where the substrate material is used as an air chamber and the graphene. A lower electrode is located in the air chamber. The lower electrode is located in the air chamber, the organic insulating film. An air chamber-organic insulating film-air chamber composite dielectric layer is formed between the organic insulating film, the dual-sided tape and the substrate materials on both sides, and participates in the internal dielectric of the sensor capacitor. USE - Laser induced graphene composite material dielectric layer based flexible pressure sensor. Uses include but are not limited to scientific research, clinical medical monitoring and pulse detection. ADVANTAGE - The capacitive pressure sensor has high sensitivity in response to micro-pressure, and a dielectric layer and two portions of the electrode can be deformable structure, multi-angle lifting sensor sensitivity and working range, and the sensor sensitivity is excellent, and with the same sensitivity under the same preparation cost, so that sensor preparation cost is far lower than other sensors, and the capacitance value is changed, the pressure in a certain range is generated in response whether the pressure is a single device pressure measurement or a multi-unit electronic skin. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic diagram of a laser induced graphene composite material dielectric layer based flexible pressure sensor.
