CSEM SA (Centre Suisse d’Electronique et de Microtechnique) is a private, non-profit Swiss research and technology organization founded in 1984 through the merger of three pioneering microtechnology institutes in Neuchâtel. With over 550 specialists, CSEM functions as an applied research, engineering, and technology transfer organization connecting academic science with industrial manufacturing.

CSEM is globally recognized for its expertise in structural design, kinematics, and compliant mechanisms. The organization pioneered friction-free flexure blade guiding systems, silicon-based micro-mechanisms (FlexMEMS), and topological design optimization for metal additive manufacturing. Its mechanism solutions are embedded in scientific instrumentation, mechanical horology, space satellites (in cooperation with ESA and NASA), and medical devices.

Founded in 1984; headquartered in Neuchâtel, Switzerland
Operates research and engineering centers in Neuchâtel, Zurich, Muttenz, Alpnach, and Bern
Over 35 years of recognized partnership with the European Space Agency (ESA)
Operates under ISO 9001 and ISO 13485 quality standards

Offer

CSEM provides custom engineering, modeling, prototyping, and validation services for precision structural mechanisms and frictionless kinematics:

Compliant Mechanisms & Flexure Structures: Frictionless, lubrication-free mechanisms based on elastic flexure blades, monolithic parallel kinematics, and interlocked lattice flexures.
FlexMEMS & Silicon Micro-Mechanisms: Deep reactive-ion etching (DRIE) batch-fabricated silicon flexures, novel horological escapements (such as Siloscape and frog escapements), and micro-resonators with zero backlash.
Design for Additive Manufacturing (DfAM): Topological structural optimization, mass-reduction engineering, integrated cabling/sensors in 3D-printed metal parts (LPBF/SLM), and compliant rotation reduction mechanisms.
Space & Scientific Instrumentation: Corner cube mechanisms, optical delay lines, mirror positioners, LiDAR scan mechanisms, and magnetic bearing stages for cryogenic and vacuum environments.
Kinematic Simulation & Metrology: Analytical multi-body dynamics, Finite Element Modeling (COMSOL Multiphysics), structural resonance tuning, and micro-vibration characterization.
