Superior sensitive, high-tensile flexible fabric film strain sensor

Xin Wang et al.

Summary: Developing strain sensors with higher sensitivity and larger monitoring range is crucial for the potential applications in intelligent electronics, motion signal analysis, and human monitoring. This study presents a high-performance flexible strain sensor fabricated by embedding silver nanowires on a carbon black-modified electrospun thermoplastic polyurethane fabric film. The sensor exhibits excellent electrical response abilities, with superior sensitivity (gauge factor >16,000) over a strain range of 360% and exceptional durability and reliability (>10,000 cycles). Mathematical fitting models are proposed to quantitatively describe the variation of conductive pathways and inter-particles distance, providing valuable insights for the manufacturing and improvement of flexible strain sensors.

Highly Conducting and Stretchable Double-Network Hydrogel for Soft Bioelectronics

Gang Li et al.

Summary: Conducting polymer hydrogels have great potential in soft bioelectronics due to their tissue-like mechanical properties and electrical interaction with tissues. However, balancing electrical conductivity and mechanical stretchability is challenging. This study addresses the issue by concentrating a poorly crosslinked precursor hydrogel with a high content ratio of the conducting polymer, resulting in a densified double-network hydrogel with high electrical conductivity and large fracture strain. The hydrogel also exhibits high biocompatibility, tissue-like softness, low swelling ratio, and desired electrochemical properties for bioelectronics. Surface grafting is used to form an adhesive layer on the conducting hydrogel, enabling robust bonding on tissues. The proposed hydrogel is applied for physiological signal recording and electrical stimulation with an in vivo rat model, showing high quality and reliability. This method provides an ideal strategy for rapid and reliable tissue-device integration with high-quality electrical communications.

PDMS-based conductive elastomeric composite with 3D reduced graphene oxide conductive network for flexible strain sensor

Xincheng Wang et al.

Summary: In this study, a flexible strain sensor based on a novel reduced graphene oxide/polydimethylsiloxane (rGO/PDMS) conductive elastomeric composite with a 3D conductive network was developed using latex assembly technique for the first time. The exclusive volume effect of the latex particles allowed selective distribution of rGO in the interstitial spaces, resulting in the formation of a 3D conductive network with an ultralow amount of rGO (0.44 vol%), making the rGO/PDMS composites mechanically robust and flexible. Each PDMS latex particle acted like an elastic balloon, aiding the destruction and reconstruction of the conductive network under external stimulus, thus providing excellent sensitivity to the sensor. The strain sensors exhibited superior sensitivity (44.01), a wide strain range (300%), and good stability (2500 cycles), enabling effective detection of human finger movements, facial muscles, voice recognition, and physiological signals.
