Crimp connection

What is a Crimp connection? In order for an SMA actuator to perform its function in the overall system, a system connection for force transmission must be ensured. Particularly in the case of pull actuators, where there is no form closure to the periphery, solutions for force transmission must be determined. In addition to the


What is DSC? Differential scanning calorimetry (DSC) describes a method of thermal analysis. It is used to determine the heat flow required to heat or cool a sample, hereby phase transformations within a material that lead to energy absorption or release detecting. In SMA technology, this method is used, among other things, to determine the

Extrinsic two-way effect

What is the extrinsic two-way effect? Effect paths and achievable stresses are lower for the intrinsic two-way effect than for the extrinsic two-way effect. In addition, an intrinsic two-way effect cannot be set for every microstructure and for many actuator geometries only at great expense. Therefore, the extrinsic two-way effect is usually used for cyclic
