  1. National Institute for R&D in Microtechnologies - IMT Bucharest http://www.imt.ro Laboratory of microsystems for bio-medical and environmental applications • NEW SENSING DEVICES • FOR IMPROVING THE QUALITY OF LIFE • Interest in FP 6 call: 'Nanotechnologies and nanosciences, knowledge-based multifunctional materials and new production processes and devices ‘ - FP6-2004-NMP-TI-4Thematic area: NMP-2004- 3.4.1.1 • Towards “converging” technologies • - new solutions to improve the quality of life e.g. by helping to alleviate the effect of disabilities or creating new types of nanotransducers • research at the frontiers of knowledge addressing nanoscience approaches together with biotechnologies and information technologies jointly with social, cognitive and/or neurosciences.

  2. National Institute for R&D in Microtechnologies - IMT Bucharest http://www.imt.ro • Expertise in: • Microsystems fabrication – design, simulation, technology, testing for chemo and biosensors: Pressure sensors; Concentration vapour sensors; Biosensors; Microelectrodes for recording neural activity; Bulk and surface micromachining; Polymeric sensitive layers for chemical and biological sensors • Process development: Wet and Electrochemical Anisotropic Etching of Silicon; Silicon Wafer Bonding; Double side alignment; Thin layers deposition (Si3N4, SiON, Polysilicon, PSG, BPSG, CVD); Spin deposition of thin film sensitive polymers

  3. National Institute for R&D in Microtechnologies - IMT Bucharest http://www.imt.ro • Projects examples: • Microprobe for recording/stimulation of the electrical activity of cells and tissues: • - Stimulating probes for many prosthetic applications should be able to deliver constant current pulses into the tissue through multiple sites precisely spaced on a substrate. • - The extracellular potential recording permits the investigation of the central nervous activity • - The compatibility between the materials used in the semiconductor fabrication and the human body was analysed.

  4. National Institute for R&D in Microtechnologies - IMT Bucharest http://www.imt.ro • Projects examples: • Calorimetric Microsensor for Methane detection based on Alumina thin Film: • - Ceramics: Alumina • - Incorporated materials in Alumina: Platinum, palladium; • - Deposition methods for thin films: spinning, sol-gel; • - Characterisation methods: X-ray, AFM, SEM • - Applications: thin layers alumina used for the fabrication of integrated sensors polymer layers with controlled film characteristics for Chemo sensors; Detection of flammable gases (e.g. methane) - domestic applications, mining industry, chemical industry and many more. Design and technological steps presentation for the calorimetric sensor

  5. National Institute for R&D in Microtechnologies - IMT Bucharest http://www.imt.ro • Projects examples: • Gas sensor SnO2 based, on alumina substrate: • - The rounded shape of the heating resistor gives an uniform temperature distribution, with the maximum temperature in the center of the circle. • - By applying voltages on the pads, the resistor heats up to 400 degrees Celsius 3D Model Full layout
