A selective electrothermal magnetic annealing technique is introduced that provides programming capabilities for mechanical micro-resonators. In the proposed approach the magnetic properties of resonators can be locally tuned in a post-fabrication batch-compatible process step. A prototype is implemented in a standard microfabrication process, where resonating ferromagnetic elements are suspend...

Industrial induction heating processes can contribute to the European Union (EU) energy saving goal of 20 percent before 2020. Induction manufacturers already propose many efficient solutions available at industrial scale. To improve induction devices for better energy efficiency, EDF R&D set up a French collaborative project called Innovative Solutions for Induction Systems (ISIS) with the fin...

This paper reports on the design of novel reactor for low-temperature growth of Vertically Aligned Carbon Nanotubes (VACNTs). Two mechanisms for selective heating catalytic nanoparticles were investigated: (i) a heating from exothermic reaction of catalytic oxidation and (ii) an induction heating. The requirements for efficient induction heating catalytic particles of size varying from micron t...

Monitoring a magnetic state using thermal or electrical activation is mandatory for the development of new magnetic devices, for instance in heat or electrically assisted magnetic recording or room-temperature memory resistor. Compounds such as FeRh, which undergoes a magnetic transition from an antiferromagnetic state to a ferromagnetic state around 100 °C, are thus highly desirable. However, ...

This paper examines a scheme for developing frequency selectable induction heating targets for stimulating temperature sensitive polymer actuators. “Frequency selectable” implies that each target has a frequency at which it heats preferentially compared to other remaining targets. Single-turn conductors whose critical dimensions are small compared to their associated skin depth (over the freque...

In polymer systems, induction heating (IH) is the physical outcome that results from exposure of selected composites embedding electrically-conductive and/or ferromagnetic fillers to an alternating electromagnetic field (frequency range: kHz MHz). The interaction applied with material accounts for creation magnetic polarization effects (i.e., hysteresis losses) eddy currents Joule losses, upon ...

A new kind of magnetic induction heating materials-carbon coated iron nanoparticles(CCINS) was prepared by arc method and they were used for cancer therapy. The measurement of nanomaterials revealed that they are super-paramagnetic and exhibit a very strong induction heating ability.The magnetic induction heating property was measured by the conduction by Bio-heat method. Heating effect of pig ...

Induction heating is a fast, efficient, precise and repeatable non-contact method for heating metals or other electrically-conductive materials. Induction heating is a process which is used to bond, harden or soften metals or other conductive materials. For many modern manufacturing processes, induction heating offers an attractive combination of speed, consistency and control. The induction he...
