Advanced Functional Materials, EarlyView.Moiré band engineering in graphene/hexagonal boron nitride–based superlattices unlocks van Hove singularities (VHSs) for terahertz (THz) optoelectronics. Tuning the Fermi level near these singularities, associated with secondary neutrality points (SNPs), enhances the photothermoelectric response.

Advanced Functional Materials, EarlyView.We propose a suture‐complementary approach that integrates optical skin clearing with a strain‐programmable luminescent adhesive patch. Hyaluronic acid promotes transdermal delivery of tartrazine to improve optical clearing and stabilizes its interaction with a photosensitizer. Optical clearing increases the penetration depth of visible light into skin,

[1993] Digests of International Magnetics Conference, 1993
A variety of distance sensors suitable for application to magnetic levitation is examined. The characteristics of the sensors regarding the phase shift between in- and outgoing signals, frequency response, DC-stability, stability to EMF interference, resolution and temperature stability are analyzed.

NanoSQUID as magnetic sensor for magnetic nanoparticles characterization
Journal of Nanoparticle Research, 2011Integrated magnetic sensors based on niobium dc SQUID (Superconducting Quantum Interference Device) for nanoparticle characterizations are presented. The SQUIDs consists of two Dayem bridges of 90 nm × 250 nm and loop area of 4, 1, and 0.55 μm2. The devices are realized by using an e-beam lithography nano-fabrication process which can directly pattern ...

On the modelling of a CMOS magnetic sensor
1994 IEEE International Symposium on Circuits and Systems (ISCAS), 1994Magnetic sensors are useful in applications such as magnetic read heads and non-contact current sensors. Ideally, a magnetic sensor should be easily integrated with its peripheral circuits. Experimental results indicate that it is possible to convert a conventional MOS transistor into a magnetic sensor by splitting the drain of the device into two ...

Magnetic sensors and their applications
IEEE Sensors Journal, 2006Magnetic sensors can be classified according to whether they measure the total magnetic field or the vector components of the magnetic field. The techniques used to produce both types of magnetic sensors encompass many aspects of physics and electronics.

Sensors Based on Magnetic Fluids
2013Magnetic fluids are materials that can be successful used in sensors and actuators as the active mass. Due to their intrinsic nature, magnetic fluids can be manipulated and controlled by suitable magnetic field which can modify their physical properties such as density and viscosity.
