Overview: Microstructure sensor is a kind of sensor with a 2D or 3D micron-scale structure prepared by advanced manufacturing technology. It is used as a sensitive part to enhance the transmission characteristics of physical, chemical, and biological signals to the environment, and convert the external signals into electrical signals. The microstructure is generally a regular or disordered structure, usually in the shape of microspheres, microcolumns, microcones, microgrooves and micropores. The microstructures with different shapes can realize the functions of puncture, pressure transmission, vibration transmission, drug transmission, bioelectric transmission, heat transmission, sound transmission, gas adsorption, and so on. In recent years, researchers from all over the world have gradually attached great importance to the research on the manufacturing technology of microstructure sensors. At present, researchers have proposed the MEMS manufacturing processes, such as reactive ion etching and chemical vapor deposition, to achieve mass manufacturing of high-precision microstructures on flexible polymer materials and rigid materials. In addition, some researchers have also proposed the manufacturing processes such as template method, self-assembly, nanoimprinting, and soft lithography to realize microstructure manufacturing. However, the above-mentioned manufacturing processes usually cannot prepare microstructure in one step, which has the problems of complex process, high production cost, limited processing materials, and unable to control the microstructure morphology. In contrast, laser manufacturing technology has the advantages of non-contact processing, no mask, customizable manufacturing, etc. By optimizing the parameters of laser process (such as laser power, scanning speed, filling mode and scanning path), it can achieve efficient and low-cost manufacturing of microstructures with different sizes and shapes. Therefore, using laser manufacturing technology to realize microstructure manufacturing and applying it to bioelectricity, temperature, and pressure sensors has become a research hotspot in microstructure sensor manufacturing technology. Laser manufacturing technology mainly includes laser ablation, laser direct writing, laser induction, laser-template processing, etc. Laser ablation is an auxiliary heating process based on the thermochemical and thermophysical effects of a laser beam, which melts the materials to be processed to realize structural forming. Laser direct writing is a manufacturing process that focuses high-energy photon beams on the materials to be processed to produce a photochemical process, and manufacturing the structures through material removal. Laser-induced modification is a manufacturing process to change the physical and chemical properties of the materials to be processed. Laser-template processing is a manufacturing process that uses a laser to produce microstructure molds on silicon, glass, polymer, and other substrates, and then uses soft lithography technology to reverse die the structures on the molds. Based on the interaction between the laser and materials, the induction, removal, and migration of materials to be processed can be realized. By adjusting the laser processing mode and processing parameters, the controlled manufacturing of the 2D or 3D microstructures or the controlled preparation of functional materials for the sensitive units can be realized, breaking through the limitations of efficiency and cost of traditional manufacturing methods for microstructures. In this paper, the types, functions, and manufacturing technologies of microstructures are summarized and classified. The preparation processes of laser manufacturing technology and other advanced manufacturing technologies of microstructures are summarized. The applications of microstructure sensors prepared by laser ablation, laser direct writing, laser induction, and laser-template processing technology in bioelectric sensing, temperature sensing, and pressure sensing are described in detail. Finally, the development trend of the laser manufacturing technology for microstructure sensors is summarized and prospected.
