Improved pressure sensing is of great interest to enable the next-generation of bioelectronics systems. This paper describes the development of a transparent, flexible, highly sensitive pressure sensor, having a composite sandwich structure of elastic silver nanowires (AgNWs) and poly(ethylene glycol) (PEG). A simple PEG photolithography was employed to construct elastic AgNW-PEG composite patterns on flexible polyethylene terephthalate (PET) film. A porous PEG hydrogel structure enabled the use of conductive AgNW patterns while maintaining the elasticity of the composite material, features that are both essential for high-performance pressure sensing. The transparency and electrical properties of AgNW-PEG composite could be precisely controlled by varying the AgNW concentration. An elastic AgNW-PEG composite hydrogel with 0.6 wt % AgNW concentration exhibited high transmittance including T550nm of around 86%, low sheet resistance of 22.69 Ω·sq−1, and excellent bending durability (only 5.8% resistance increase under bending to 10 mm radius). A flexible resistive pressure sensor based on our highly transparent AgNW-PEG composite showed stable and reproducible response, high sensitivity (69.7 kPa−1), low sensing threshold (~2 kPa), and fast response time (20–40 ms), demonstrating the effectiveness of the AgNW-PEG composite material as an elastic conductor.

Contour Mode

This paper presents zinc oxide one port contour-mode machined resonator operated under global system for mobile communication range of frequency. TheS11 value of –38.57 dB at resonance frequency of 882 MHz in average was observed. The phase shift of the device and voltage standing wave ratio were noted as 115° and 1.18 respectively, sufficiently adopted for radio frequency communication. The device has been optimized for 21 aluminum interdigited fingers patterned over zinc oxide thin film. Two electron beam and two optical lithography were processed for fabricating the devices. Our findings are expected to provide effective approach for realizing efficient biocompatible detector for biomedical mass/pressure sensing application.
