Skin-like flexible pressure sensors with good sensing performance have great application potential, but their development is limited owing to the need for multistep, high-cost, and low-efficiency preparation processes. Herein, a simple, low-cost, efficient laser-induced forming process proposed first time prepare skin-like piezoresistive sensor. In process, based on photothermal effect of graphene foaming glucose, polydimethylsiloxanes (PDMS) film porous structures surface protrusions obtained by using infrared laser irradiation glucose/graphene/PDMS prepolymer film. Further, PDMS conductive layer, new sensor obtained. Due stress concentration caused low stiffness structures, realizes an ultrahigh sensitivity 1348 kPa–1 at 0–2 kPa, wide range 200 fast response/recovery 52 ms/35 ms, stability over 5000 cycles. The detection human pulses robot clamping force indicates its potential health monitoring soft robots. Furthermore, in combination neural network (CNN) algorithm artificial intelligence technology, achieves 95% accuracy speech recognition, which demonstrates intelligent wearable electronics. Especially, expected facilitate efficient, large-scale devices multilevel structures.

Continuous developments in the field of 3D printing techniques and equipment have enabled their usage electronics structures, circuits, device fabrication addition to many other fields. This advancement has potential sensors using silicon-based micro or even Nanoelectronics. Currently, manufacturing packaging such devices structures are heavily reliant on lithography, which can be slow involve substantial processing requirements. In this paper, a temperature-sensing Interdigital Transducer (IDT) structure was designed fabricated Direct Laser Writing (DLW) based Two-Photon Lithography (TPL), is high-resolution technology. The TPL positive photoresist combined with physical vapor deposition method lift-off process create gold IDT microstructures. developed sensing were characterized network analyzer determine resonance frequency its dependence temperature changes. results showed that exhibit linear response toward changes an average sensitivity 0.123 MHz/°C. most important advantage producing additive technique very small-sized produced error-free efficiently.
