Feng Yi (Fed)

Materials Research Engineer

Feng Yi is a Materials Research Engineer in the Materials Measurement Science Division of the Material Measurement Laboratory at the National Institute of Standards and Technology.  He works on the development of MEMS based thermal sensors for materials characterization, and integration of the thermal sensors into different instruments to extend the measurement capability, for example, a thermal sensor coupled with a mass spectrometer to simultaneously measure the evolved gas species and thermal events during the thermal cycles.

MEMS based thermal sensors, often referred as nanocalorimeters, are used to measure small samples with high speed and high sensitivity, and offer the potential of high throughput approach.  The sensors are miniature and feasible to integrate with other instruments.

Research Interests

  • MEMS based sensors
