Magnetic Shape Memory Microactuators
By introducing smart materials in micro systems technologies, novel smart microactuators and sensors are currently being developed, e.g., for mobile, wearable, and implantable MEMS (Micro-electro-mechanical-system) devices. Magnetic shape memory alloys (MSMAs) are a promising material system as they show multiple coupling effects as well as large, abrupt changes in their physical properties, e....
متن کاملMagnetic shape memory: Magnetoelastic sponges.
news & views Nevertheless, a few hurdles must be overcome before SBA dielectrics will make a significant impact on large-scale transistor manufacturing. Perhaps the biggest problem at the moment is the slow response of the sodium ions to an external electric field. Consequently, the capacitance of the SBA films is reduced at higher frequencies. Solid-polymer electrolytes typically suffer from a...
متن کاملMagnetic Shape Memory Actuators for Fluidic Applications
Magnetic Shape Memory (MSM) actuators represent a new type of smart electromagnetic actuators where the MSM material elongates and contracts in a magnetic field. The MSM material has the ability to change its size or shape very fast and many million times repeatedly. Based on internally designed and produced Magnetic Shape Memory materials, the ETO GROUP has developed its new MAGNETOSHAPE® tech...
متن کاملMagnetic Shape Memory Alloy and Actuator Design
In the field of micromechatronics, microrobotics and specially microfactories, active materials are used in most cases. They permit high resolution and distributed actuation. In this area, Magnetic Shape Memory Alloys (MSMA) are possible candidates. If a lot of studies deal with MSMA, only few applications use them until now. MSMA are attractive active materials because they have large strain (...
متن کاملMagnetic Moment of Cu-Modified Ni2MnGa Magnetic Shape Memory Alloys
The magnetization measurements at 5 K were carried out for Ni2Mn1 − xCuxGa (0 ≤ x ≤ 0.40) and Ni2MnGa1 − yCuy (0 ≤ y ≤ 0.25) alloys. All of the magnetization curves are characteristic of ferromagnetism or ferrimagnetism. By using Arrott plot analysis the spontaneous magnetization of all samples was determined from the magnetization curves. The magnetic moment per formula unit, μs, at 5 K was es...
