Optical MEMS solutions

All-optical MEMS sensors are ideal for applications involving harsh environments, distributed networks and remote sensing.

CEKO sensors fabricates microchip based sensors with integrated optical structures for strain, acceleration and pressure sensing for e.g. renewable energy, marine and off-shore.

Utilizing refractive index modulation™ technology for high sensitivity, reliability and flexibility CEKO sensors are applicable in a large range of sensing scenarios.

Example applications include structural health monitoring and production optimization on wind turbine blades, pressure and acceleration sensing in oil production and monitoring of forces and pressures on aircrafts.

Technology

The all-optical MEMS sensor technology is typically implemented in the form of an accelerometer, but it is applicable to a number of related sensor concepts including pressure sensors, microphones, force sensors, temperature sensors, strain sensors and chemical sensors. The technology is based on reflection of light from a Bragg grating structure, however, using a completely different physical principle than FBG sensors. This concept allows for significant improvements in sensor specifications. It is at the same time compatible with existing FBG systems.
