Magnetic field sensors are devices that detect and measure magnetic fields around permanent magnets, electrical conductors, and electrical devices. As such, they are particularly relevant for applications in IoT, 5G, smartphones, energy, and biomedical engineering. In this context, dedicated research is being carried out on novel thin film composite magnetoelectric (ME) sensor concepts for the...
The microwires due to their dimensions have a huge potential in wide fields from agricultural, medical, and technological high-end applications such as sensors or actuators. On the one hand, designing different types of materials for each application is possible. On the other hand, there is the scalability of dimensions, which brings opportunities to control the physical properties of the...
Magnetoactive elastomers (MAEs) consist of an elastic matrix with embedded micron-sized soft and/or hard magnetic particles. Such elastomers change their mechanical and rheological properties under the influence of external or internal magnetic fields. The magnetization of MAEs with hard magnetic particles in a strong magnetic field enables to produce elastic permanent magnets.
Magnetized...
Biomedical applications typically require very low noise magnetic sensors, since the magnetic field to be measured are usually very small. Traditionally SQUIDs have been the only sensors able to reach noise levels low enough to be employed in this field. However, the necessity of cryogenic temperature limits the applications of these sensors to fields where extremely low noise is required....
Performance of planar Hall magnetoresistive (PHMR) sensors was measured in different specification, such as sensor layer thickness, geometry [1].

In this magnetic encoder experiments, PHMR sensor was located near to steel gear and permanent magnet was located behind the PHMR...
Our research explores the potential use of semiconductor thin-film materials and graphene-based structures for magnetic field detection in harsh environments, particularly in thermonuclear reactors.

Developing portable sensors is crucial for improving the detection of biological agents. These devices enable rapid, on-site analysis, providing real-time monitoring that is vital for applications such as disease diagnosis and environmental monitoring or the pathogen detection including viruses and bacteria. Portable sensors are compact, lightweight, and easy to use, making them suitable for...
Among other gases, the detection of relative humidity (RH) is crucial in air quality monitoring, food storage or industrial processes control. We present here a wireless humidity sensor based on the magnetoelastic resonance (MER) phenomenon. MER sensors are usually made of magnetostrictive ribbons, which can be driven to mechanical resonance via magnetic field excitation. The basis of their...
Composite magnetic materials have been explored for several applications ranging from biomedical to robotics [1]. The ability to incorporate homogeneous and dense nanoparticles in elastomer matrix creates opportunities for the integration with magnetic sensors in flexible electronics [2], providing viable for large area applications. In addition, biocompatibility between the elastomers and...
When designing a magnetic tunnel junction (MTJ) sensor, Key Performance Indicators (KPIs) such as sensitivity, linear operating field range and electrical resistance are set by the application specifications. One of the critical design parameters to tune is the geometry of the MTJ device, as shape, dimension, and aspect ratio directly impact KPIs [1]. By choosing the geometry of the device, it...
Spin-orbit torque (SOT) provides a fast and efficient way to manipulate the magnetization in magnetic devices such as magnetoresistive random access memory (MRAM) [1]. These devices take advantage of the strong spin-orbit coupling (SOC) in the bulk or at the interfaces of heavy metal (HM) layers to generate spin polarized currents. The spin currents are injected into an adjacent ferromagnet...
Magnetoresistive magnetic sensors play a key role in sensing magnetic fields at room temperature, with applications spanning from information storage to biomagnetism. Extraordinary magnetoresistive (EMR) sensors are a promising class of magnetoresistive sensors, which exhibit a magnetoresistance on the order of $7.5\times 10^5\,\%$ at 4T [1]. The extraordinary magnetoresistance is a...
