Smart actuator materials
AdaptaMat develops and utilizes MSM materials, which produce a change of dimension, shape or stress due to an applied magnetic field.
Magnetic Shape Memory effect is a new invention in actuator materials field, allowing even 50 times greater strains than in previous magnetically controlled materials (magnetostrictive materials). In MSM materials the magnetic field moves microscopic parts of the material (so called twins) that leads to a net shape change of the material. The mechanism enables also more complicated shape changes than conventional linear strain, such as bending and shear. Strains can be even 10 % (depending on the material). AdaptaMat's commercial MSM materials produce typically 3,5 % reversible strain at 0 to 2 MPa stress in actuator use.

Currently we produce and sell MSM material pieces (MSM sticks) in rectangular or square shapes. Minimum dimension is 0.1 mm and maximum 40 mm. For larger shapes laminated structure can be used. Upon request, other shapes (disk,rod,etc.) can be manufactured. We also produce MSM actuators for research use and can provide our expertise to selected customers in R&D projects, using the MSM material and e.g. building demonstration devices.
MSM materials’ field of application seems to be very wide, ranging from automotive applications to home electronics. Complicated mechanical structures can be simplified by using MSM materials. Consider a sewing machine: traditional sewing machine has a rotating electric motor and a large number of parts in a rather complicated mechanical transmission system, although the desired motion of the needle is up and down. A sewing machine based on MSM technology could consist of an electromagnet (coil) and a needle made of MSM-material.
Revolution of Electromechanics
Magnetically controlled shape memory materials (MSM) replace machines
AdaptaMat has patents issued and pending to MSM mechanism and applications in several countries. In addition to developing MSM materials ourselves, we are also sponsoring and taking part to research projects in, e.g., Helsinki University of Technology (Espoo, Finland) and MIT (Boston, MA, USA). MSM materials can provide new solutions to many future products where electricity or magnetic field is used to create motion or force.
