Reaction wheels
In a reaction wheel, a mass is attached to a motor. If the motor is driven in zero gravity and the mass is set in rotation, this also generates a counter rotation of the rest of the carrier.
Reactive ion deep etching
Reactive ion deep etching (also known as the Bosch process) is a dry etching process that produces a particularly anisotropic etch profile. Through an iterative process sequence of etching and passivation, the sidewalls of the material can be protected in already etched cavities, creating very deep structures.
Reactive ion deep etching
Reactive ion deep etching – also known as the Bosch process – is a dry etching process that can be used to create anisotropic etch profiles in silicon. This is possible thanks to the two steps, etching and passivation, which are carried out alternately.
Selective Laser Melting (SLM)
Selective Laser Melting (SLM) is an additive manufacturing process (3D printing) in which powdered material is deposited layer by layer onto a base plate and melted using laser radiation. Today, the designation Laser Powder Bed Fusion (LPBF) is mainly used.
Shape memory alloy
Shape memory alloys (FMA) are metals with two different crystal structures, the so-called phases, depending on the temperature: The high-temperature phase called “austenite” and the low-temperature phase called “martensite.” If the temperature changes, the crystal lattice and thus the shape of the component changes to one of the two crystal structures. This allows FGL to […]
Sonotrodes
Sonotrodes are tools that are set into resonant vibration by the introduction of high-frequency mechanical oscillations.
Stent
A stent is a vascular support made of metal or synthetic fibers inserted into vessels or hollow organs to support them or keep them open.
Stereolithography
Stereolithography is a lithographic 3D printing process for producing components from liquid plastic. The plastic is irradiated with ultraviolet light or ultra-short laser pulses, for example, and cured layer by layer with pinpoint accuracy.
Synthetic driving data
Synthetic data is artificially generated data. This information does not come from real sources, but was generated using simulations and algorithms.
Torsion
In torsion, a force acts on a body and twists it, creating stress.
