To overcome this limitation, we present an ultrasound-compatible sEMG electrode fabricated from a silver nanowire–polydimethylsiloxane (AgNW– PDMS) composite. Electrode combines electrical conductivity with acoustic transparency, enabling co-localized acquisition of electrophysiological and mechanical muscle signals. Phantom and human experiments were performed using a Verasonics Vantage 256 system with a linear array transducer. Results demonstrate that the AgNW–PDMS electrode introduces an attenuation of about 33 % while retaining sufficient displacement for ARFI stiffness estimation. Simultaneous ARFI data were successfully collected from the extensor carpi radialis muscle in healthy participants without repositioning. To our best knowledge, this study provides the first demonstration of co-localized sEMG and ARFI acquisition enabled by acoustically transparent electrodes. While polydimethylsiloxane (PDMS) introduces acoustic limitations due to attenuation and impedance mismatch, this work establishes a foundation for multimodal neuromuscular monitoring and motivates systematic material optimization.}, author={Moon, Sunho and Xue, Xiangming and Ganesh, Vidisha and Akbari, Ali and Muhtadi, Sabiq and Qazi, Shureed Deepro and Yokoyama, Keita and Zhu, Yong and Gallippi, Caterina and Sharma, Nitin and et al.}, year={2025}, month={Sep} }
