A control and operating element has at least one dielectric elastomer sensor in which at least two electrode layers, between which a capacitance can be measured, are separated from one another by an at least partially elastomeric dielectric. The sensor has a preset position and can, due to a deformation of elastomeric components, adopt one or more working positions in which the capacitance is changed with respect to the preset position and which is/are reached due to application of an external force. The control and operating element further has a triggering mechanism which can trigger an event that is associated with a reached working position.

Elastomer-based capacitive control and operating element

A forming method includes using at least one forming tool to form a material of a workpiece and using a lubricant between the material and the at least one forming tool. The lubricant has a viscosity that is modifiable by applying or varying a field.

Magnetorheological lubricant for metal forming processes

The present invention discloses a magnetorheological force transmission device which comprises at least two solid body parts adapted to be moved in a substantially translational manner against each other, and an MRF gap, which is at least partially fillable and/or filled with a magnetorheological materialMRF, the MRF gap being arranged at least partially inside one of or both of the two parts and/or being arranged at least partially in-between the two parts, and which is characterized in that the magnetic circuit system of the magnetorheological force transmission device being designed and/or disposed to generate a magnetic flux within at least part of the MRF gap comprises at least one electromagnet, at least one permanent magnet and at least one magnetic-field-balancing insert and/or magnetic isolator.
