Abstract In the past decade, there has been a significant rise in development of novel spintronic device architectures specifically designed to meet demands diverse biomedical applications. These advancements have notably focused on enhancing various bioassay detection techniques, including magnetocardiography and neural signal recording. Through collaboration within spintronics community, these devices are rapidly transitioning from laboratory prototypes practical applications, catering applications benefiting both researchers medical practitioners alike. this review, we comprehensively explore devices, due their inherent sensitivity external magnetic fields, ease fabrication into large arrays nano/micro-sized confined spaces, resilience under harsh environmental conditions, high repeatability. Established that exploit magnetoresistive effects already extensively deployed as biosensors for disease diagnosis, imaging, bio-magnetic field detection, offering superior robustness. This review aims provide peers with an up-to-date overview contexts while also commenting future research trends challenges. With nano/microfabrication techniques robustness sensitivity, it is foreseeable could catalyze revolutionary transformations healthcare.

The magnetic field produced by the heart's electrical activity is called magnetocardiogram (MCG). first 20 years of MCG research established most concepts, instrumentation, and computational algorithms in field. Additional insights into fundamental mechanisms biomagnetism were gained studying isolated hearts or even pieces cardiac tissue. Much effort has gone calculating using computer models, including solving inverse problem deducing bioelectric sources from biomagnetic measurements. Recently, magnetocardiographic focused on clinical applications, driven part new technologies to measure weak fields.

Abstract Objectives This study evaluates micro-electro-mechanical systems (MEMS) devices comprising cantilever piezoelectric resonators with powder-based permanent magnets (micromagnets) at the tip. Fabricated using a well-known PowderMEMS process given by Fraunhofer Institute for Silicon Technology, these function as magnetic field sensors based on torque detection principle, which arises from interaction between micromagnets’ dipole moment and to-be-measured field. The investigates how state of micromagnets influences overall sensitivity provided Prototype MEMS-devices. Methods performance first prototypes this narrow-band sensor was evaluated two approaches: (1) Vibrating Sample Magnetometer (VSM) to analyze hysteresis loop (2) measurements resonance frequency determine under predefined external flux density. Results Among four analyzed, device highest remanence coercivity demonstrated superior sensing performance, achieving 1,090 kV/T frequency. analysis showcased substantial variations in noise amplitude spectral density, sensitivity, emphasizing importance properties performance. Conclusions These findings highlight potential MEMS-devices enhanced capabilities compact designs, particularly useful array configurations narrow-bandwith medical applications.

Heart diseases remain one of the leading causes morbidity and mortality worldwide, necessitating innovative diagnostic methods for early detection intervention. An electrocardiogram (ECG) is a well-known technique preliminary diagnosis heart conditions. However, it can not be used continuous monitoring due to skin irritation. It well known that every body organ generates magnetic field, peak amplitudes about 10 100 pT (measured at distance 3 cm above chest). This poses challenges capturing such signals. paper reviews different techniques capture heart's signals along with their limitations. In addition, this provides comprehensive review approaches use heart-generated field diagnose several diseases. research reveals two aspects. First, as noninvasive tool, signal lead more sensitive advanced disease tools, especially when possible affordable. Second, its current limited lack accurate, affordable, portable sensing technology.
