Stretchable surface electromyography electrode array patch for tendon location and muscle injury prevention

Nature Communications, Journal Year: 2023, Volume and Issue: 14(1)

Published: Oct. 14, 2023

Surface electromyography (sEMG) can provide multiplexed information about muscle performance. If current sEMG electrodes are stretchable, arrayed, and able to be used multiple times, they would offer adequate high-quality data for continuous monitoring. The lack of these properties delays the widespread use in clinics everyday life. Here, we address constraints by design an adhesive dry electrode using tannic acid, polyvinyl alcohol, PEDOT:PSS (TPP). TPP offers superior stretchability (~200%) adhesiveness (0.58 N/cm) compared electrodes, ensuring stable long-term contact with skin recording (>20 dB; >5 days). In addition, developed a metal-polymer array patch (MEAP) comprising liquid metal (LM) circuits electrodes. MEAP demonstrated better conformability than commercial arrays, resulting higher signal-to-noise ratio more recordings during movements. Manufactured scalable screen-printing, MEAPs feature completely stretchable material architecture, enabling real-time monitoring stress, fatigue, tendon displacement. Their potential reduce injuries enhance performance daily exercise professional sports holds great promise.

Abstract Bio‐based hydrogels, valued for their flexibility, tunable mechanical properties, and biocompatibility, are promising materials wearable skins sensing devices in bionic hand control systems. Lignin, a biopolymer rich functional groups, can be modified into UV‐curable monomers, enabling the development of 3D‐printed hydrogels via photopolymerization. However, inherent rigidity lignin's aromatic rings, coupled with covalent cross‐linking between lignin other often limits hydrogel's stretchability (poor strain) compressibility. Additional challenges, including poor moisture retention freeze resistance, further hinder wider application. In this study, lignin‐based hydrogel is developed high tensile strain (≥350%), compressive (≈95%), fatigue resistance (up to 10 000 cycles under 50% strain, 200–800 95% strain), which achieved by incorporating glycerol lithium chloride facilitate dynamic hydrogen ion bonds, while accordingly reducing sites monomers. The enhanced allow effective performance at −40±1 °C. Afterward, using 3D printing technology, sensors ripple‐shaped 3 × Matrix pressure fabricated, demonstrated uniform stress distribution improved controlling complex movements, underscoring application advancing human–machine interfaces.
