Flexible magnetoelectronic is a new and yet-to-be-explored path for future biomagnetic sensing especially to detect the ultra-low human magnetic field using magnetic field sensors. Most of the recent approaches have been framed using magnetoresistive (MR)- sensors, benefiting their fascinating applications, especially in the field of biomagnetism and advanced health monitoring systems, and unveiling several prospective and applicative domains. In this perspective, flexible MR sensing technology emerges as a new horizon in skin sensorics for recording and imaging various human electrophysiological phenomena such as magnetocardiography (MCG), magnetomyography (MMG), and magnetoencephalography (MEG). Despite its promising futuristic applicability in biomagnetism and healthcare monitoring system, this sensing technology manifests several technical challenges, which limits its versatile functionality, and needs to be addressed properly for the development of NEXT-GEN healthcare technology and biomedical or biomimetic devices.
In this proposed research, we intend to study the magnetic manifestation of human muscle activity, coined as MMG using an ultrathin flexible planar Hall-effect (PHE) sensor, which has not been explored or tested before. We aim to develop an efficient flexible sensing technology that enables us to detect a few pico-Tesla (pT)/ femto-Tesla (fT) signals at room temperature and demonstrates a feasible approach to reinvigorating the MMG technique. The proposed research directives also address the most awaited state-of-the-art sensing solutions to overcome the existing technical limitations in myograph recording. Moreover, this sensing technology offers qualitatively miniatured, flexible, and implantable futuristic MMG sensing devices and paves the way towards full-fledged on-skin touchless biocompatible interactive human-machine interfaces. In the next stage, we aim to extend this research for challenging MEG applications.ver más
