▎ 摘　　要

NOVELTY - The calculator has an adjustable resistor (4) for dividing pressure. A bread board (5) is connected with a STM32 single chip (6). Sides of a sensing unit (1) are coated with layers of flexible packaging layer. The flexible packaging layer is Polydimethylsiloxane (PDMS) coated on the surface of the laser induced graphene. The PDMS is prepared by mixing and stirring dimethyl silicone polymer and curing agent. The sensing unit is prepared by infrared laser-induced graphene transfer printing. USE - Laser-induced graphene-based flexible calculator. Uses include but are not limited to a touch display, soft robot, electronic skin and a military medical field. ADVANTAGE - The calculator has flexible characteristics, and is convenient to carry. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a laser induced graphene-based flexible calculator. 1Sensing unit 2Lead 4Trigger resistor 5Bread board 6STM32 single chip
