Noliac Actuators: Bending (CMB)

Noliac Technology

Noliac's line of Ceramic Multilayer Benders (CMB) products is based on the company's advanced multilayer technology, harnessing the full potential of the piezoelectric effect at very low operating voltages.

Multilayer piezoelectric benders are single co-fired ceramic components with ceramic layers and internal electrodes configured as to generate a bending mode.

The most common bender geometry is a narrow rectangle (CMBP) with typical performance range up to +/- 1500µm stroke and up to 10N blocking force.

Noliac has also developed a unique ring shape bender (CMBR) with typical performances range up to +/- 150µm and up to 100N blocking force.

Multilayer benders are used in numerous applications within e.g. optics, telecommunication, instrumentation, automotive, valves.
