Abstract Muscle on a Chip devices are valuable research tools for interrogating the structure and physiology of engineered heart, skeletal, or smooth muscle tissue constructs from molecular to multi‐cellular level. However, many existing rely functional assays with limited throughput, such as optical microscopy, measure contractility. Although electrical components have been integrated automate recordings in advanced devices, their fabrication typically requires specialized equipment found cleanroom facilities. In this work, miniature strain gauges record contractions skeletal bundles using only benchtop equipment. A commercial CO 2 laser is employed generate patterns laser‐induced graphene (LIG) polyimide (PI) films. LIG then transferred PI thin polydimethylsiloxane (PDMS) films make conductive intrinsically flexible stretchable layers that demonstrate long‐term stability under repeated cycles stretch. Engineered anchored LIG‐PDMS contraction sensed response stimulation, which delivered by LIG‐PI stimulation electrodes also into device. Collectively, these results an attractive material rapidly inexpensively integrating situ sensing devices.

The study presents a first electrochemical method for the determination of immunomodulator drug Baricitinib (BARI), crucial in managing COVID-19 patients requiring oxygen support. A unique electrode was developed by modifying graphite carbon nickel nanoparticles (NiNPs) with functionalized multiwalled nanotubes (f.MWCNTs), resulting nanohybrids tailored highly sensitive BARI detection. Comparative analysis revealed superior electrocatalytic performance nanohybrid-modified over unmodified counterparts and other modifications, attributed to synergistic interactions between f.MWCNTs nanoparticles. Under optimized conditions, sensors exhibited linear detection within concentration range from 4.00 × 10–8 5.56 10–5 M, remarkably low limit 9.65 10–9 M. Notably, modified displayed minimal interference common substances demonstrated high precision detecting plasma medicinal formulations, underscoring its clinical relevance potential impact on treatment strategies.
