NOVELTY - Preparing flexible pressure sensor with programmable shape, comprises: (i) preparing polyethylene glycol diacrylate aqueous solution; (ii) adding conductive functional material dispersion liquid into polyethylene glycol diacrylate aqueous solution to obtain conductive functional material polyethylene glycol diacrylate reaction liquid, and reacting in an ice bath; (iii) adding ammonium persulfate solution and tetramethyl ethylene diamine solution to the final liquid obtained in step (ii) to obtain a precursor solution, and rapidly pouring the precursor solution into a mold; (iv) moving the mold to a copper column, contacting the bottom of the copper column with liquid nitrogen until the precursor solution is completely frozen; (v) freezing and polymerizing the final reaction system of step (iv), and freeze-drying to obtain anisotropic aerogel; and (vi) coating the upper and lower surfaces of the aerogel with conductive silver paste, and connecting wire with the digital multimeter probe. USE - The flexible pressure sensor with programmable shape is useful in wearable pressure sensor (claimed), medical care, human-machine interface, wearable electronic device, robot and internet of things. ADVANTAGE - The method introduces the shape memory performance into the flexible pressure sensing material design, endows the device shape programmable function, hence the wearable pressure sensor can shape self-adaptive with complex curvature of the detection part and improve the accuracy of the device detection signal. The shape-programmable flexible pressure sensor is deformed from the 2-D plane shape to the 3-D shape, and achieves the application of the cooperative deformation with different wearing positions. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of the flexible pressure sensor, comprising: (a) the setting the flexible pressure sensor to the target shape state; (b) changing the target shape state to obtain the temporary shape state; and (c) under application scene, recovering the target shape state by external stimulation, and self adaptively wearing the flexible pressure sensor on the specific wearable position.
