Protocol for preparation of a textile magnetoelastic generator patch
Year: 2024
Type: article
Abstract: The magnetoelastic generator (MEG) is a fundamentally new platform technology to convert mechanical motions into electrical signals for sensing, therapeutics, and energy applications. Here, we present a protocol for fabricating and characterizing the MEG for personalized muscle physiotherapy when integrated into a wearable textile patch. We describe the steps for fabricating such a textile MEG, including the magnetomechanical coupling (MC) and magnetic induction (MI) layers, and characterizing their magnetoelastic and electrical properties. We then detail procedures for monitoring muscle biomechanical activities and muscle physiotherapy application. For complete details on the use and execution of this protocol, please refer to Xu et al. 1 • Fabrication strategy and structure characterization of a magnetoelastic generator • Examination of the electrical performance of the textile magnetoelastic generator patch • Application in monitoring muscle movements based on the produced electrical signals • Quantification of loading deficits and excesses based on the lab-scale equation Publisher’s note: Undertaking any experimental protocol requires adherence to local institutional guidelines for laboratory safety and ethics.
