A fully soft, self-powered vibration sensor by laser direct writing

Wireless, Smart Hemostasis Device with All‐Soft Sensing System for Quantitative and Real‐Time Pressure Evaluation

“…EGaIn, a kind of room temperature LM, is an ideal soft electrode for application in soft electronics. [28][29][30][31][32][33] As shown in Figure S1 (Supporting information), the electronic part consists, more specifically, of a thin printed circuit board (PCB) based on an 80 μm thick middle polyimide supporting layer with 18 μm thick patterned copper (Cu) traces on the top and bottom surfaces. Immersion gold is used upon annealed Cu for more reliable solderability in the extra process.…”

Turning trash into treasure: recent advances in triboelectric nanogenerator based on waste-derived carbonized materials

“…The laser heats the surface at a rate of up to 1000 °C s −1 , rapidly generating extremely high temperatures; this is followed by carbonization and graphitization to form porous graphenes, which are low-cost, environmentally friendly, and biodegradable WDCMs. 61,62 Such WDCMs exhibit excellent conductivity, high electronic density, and mechanical exibility; they can serve as thin-lm electrodes in the conductive layers of TENGs. Moreover, the charges generated by friction can be transferred without the use of adhesives or conductive agents.…”

A facilely prepared notch-insensitive nanocomposite organohydrogel-based flexible wearable device for long-term outdoor human motion monitoring and recognition

“…45 Luo et al designed a fully soft, self-powered vibration sensor with wireless transmission for motion monitoring, which effectively distinguishes slipping from walking, jumping and running. 46 Zhang et al proposed a laser direct writing method to fabricate flexible piezoresistive sensors with microstructures on PDMS/ MWCNTs composites, which can be applied in LED brightness control, pulse detection and voice recognition. 25 Last but not least, the recognition of different human motion signals can effectively remind the wearers, especially the aged or the disabled, to pay attention to their motion state or get ready for the corresponding safeguard.…”
