Flexible pressure sensors play an extremely important role in the fields of intelligent medical treatment, humanoid robots, and so on. However, low sensitivity small initial capacitance still limit its application development. At present, method constructing microstructure dielectric layer is commonly used to improve sensor, but there are some problems, such as complex process inaccurate control microstructure. In this work, ion composite photosensitive resin based on polyurethane acrylate ionic liquids (ILs) was prepared. The high compatibility ILs achieved by adding a chitooligosaccharide (COS) chain extender. optimized digital light processing (DLP) 3D-printing. Due introduction construct electric double (EDL), flexible sensor exhibits 32.62 kPa−1, which 12.2 times higher than that without ILs. It also has wide range 100 kPa fast response time 51 ms. good under different pressures can realize demonstration human health.

Photocurable Foam for Three-Dimensional-Printed Porous Structures

ACS Applied Materials & Interfaces, Год журнала: 2024, Номер 16(34), С. 45589 - 45597

In this research, a foam three-dimensional (3D) printing method using digital light processing (DLP) technology was developed to fabricate 3D-printed porous structures. To address the challenges in preparing DLP precursor fluid, we designed specialized foaming device. This device enables solution be blended with air, resulting stable an adjustable air/liquid fraction and suitable fluidity, crucially enhancing gas–liquid contact time for process. By manipulation of fluid flow rates, cycle counts, gas/liquid ratios, one can easily prepare uniform foams precise control over pore size porosity. avoid significant volume reduction during ultraviolet (UV) curing, nanoparticle fillers were introduced into network prevent collapse structure. Furthermore, inclusion UV absorber enhanced quality process by addressing limitations associated particle scattering reflection. The readily intricate structures, featuring planar resolution below 30 μm accuracy less than 1%. Several examples also demonstrated highlight advantages its ability directly print custom thereby saving material resources.
