MEMS Sensors

  • VTT has been a forerunner in developing low noise and temperature stable resonators since 1999.

  • VTT MEMS based 3D magnetometer is developed both for consumer applications and for fusion power plant ITER.

  • VTT has a world record in MEMS sensor stability. Measured stability of the ac voltage reference was ± 2 ppm over one month.

Mission

MEMS technology provides a cost efficient way to produce sensors in high volumes. However, development costs and lack of ramp-up production facilities makes the development of new sensors challenging. Our team is part of VTT High Performance Microsystem value chain that offers a seamless one stop service from idea to production. The customer benefit realizes in faster development time and reduced R&D cost.
