This work deals with thermal simulation and characterization of solid state lightening (SSL) LED Lamp in order to get precise 3D thermal models for further lamp thermal optimization. Simulations are performed with ANSYS-CFX and CoventorWare software tools. The simulated thermal distribution has been validated with thermal measurement on a commercial 8W LED(More)
This study describes an integrated NH3 sensor based on a hydrogenated nanocrystalline diamond (NCD)-sensitive layer coated on an interdigitated electrode structure. The gas sensing properties of the sensor structure were examined using a reducing gas (NH3) at room temperature and were found to be dependent on the electrode arrangement. A pronounced response(More)
The paper describes design of an anemometric sensor system for measurement of velocity and direction of airflow over a chip. A CMOS transistor has been used as the temperature sensor. Temperature “heater” has been designed as an integrated resistor. The direction of airflow is computed from the orthogonal arrangement of temperature matrix. The matrix is(More)
Sensors for the measurement of mechanical deformation are frequently used in industrial measurements. The sensors are realized using different technologies. The sensors of the type strain gauge is utilized for the measurement of change in length of geometrical dimensions. The strain gauge is realized on a thin cantilever structure. Piezoresistive strain(More)
