Lightweight, superhydrophobic, lignin-based polyurethane foam composites for underwater pressure sensing

“…3f and Table S1 (ESI †), this SCFS has a comparably high sensitivity in the range of 0-25 kPa. 20,22,[38][39][40][41][42][43][44] The stability of the SCFS is shown in Fig. 3g and Fig.…”

“…21 Chen, et al prepared high-performance, superhydrophobic sensors with ridge-like microstructures made using silver nanoparticles, which were successfully employed to detecting various anthropogenic signals with real-time detection of diverse activities, including application in underwater environments. 22 These flexible sensors prepared from polymers such as PDMS, commercial polyurethane, and melamine-formaldehyde were coated or stacked with conductive materials on their respective surfaces. However, the conductive components prepared by impregnation or coating methods are unstable and vulnerable to environmental impact, resulting in the falling off of the conductive elements on the surface and exposing the internal non-conductive parts.…”

Bamboo-Inspired, Environmental Friendly PDMS/Plant Fiber Composites-Based Capacitive Flexible Pressure Sensors by Origami for Human–Machine Interaction

“…To this end, researchers have carried out abundant work on dielectric layer microstructure design and sensitive material preparation. Devices fabricated with microstructures such as pyramids and bionic structures, prepared by using highly elastic sponges, flexible fabrics, and 3D-printed molds as templates, have achieved a high level of sensitivity and a low limit of detection, as well as materials such as carbon nanotubes, reduced graphene oxide, , and MXenes . Different preparation techniques demonstrate distinct characteristics and can offer designable properties (including spraying and self-diffusion, vacuum freezing method − ).…”

Rapid Fabrication of High-Performance Flexible Pressure Sensors Using Laser Pyrolysis Direct Writing

“…Consequently, the resistance network, consisting of material resistance and contact resistance within the sensor, changes with the localized strain, enabling the detection and identification of pressure. 15,16 Advanced materials, including carbon nanotubes, 17 carbon nanofibers, 18 graphene, 19,20 MXene, 21,22 metal nanowires, 23 and nanoparticles (NPs), 24 have been widely applied as sensing elements to create electrical percolation pathways. In addition, flexible materials such as poly(dimethylsiloxane) (PDMS), 25 polyimide (PI), 26 poly(ethylene terephthalate) (PET), 27 polyethylene (PE), 28 and polyurethane (PU) 29 serve not only as flexible substrates for active materials but also as flexible electrodes, which can be fabricated through methods like infilling, 30 coating, 31 and modification.…”
