Electronics, microelectronics & sensors

The main activities of Protech are focusing on application oriented technologies development, based on know-how and expertise of leading Lithuanian researchers and technologists. Joint research activities with Vilnius Gediminas Technical University, Institute of Biochemistry and Institute od Ecology give promissing results in the RTD fields of chemical ecology and chemosensory systems. Areas of activities of Protech cover:

• Electronic systems
• RTD in sensors and biosensors technology
• Development and application of the sensors-based measurement systems including e-nose and sensors signal processing and fusion
• Femtosecond laser beam positioning and manipulation

Programs

Protech staff participated implementing a national four years Programme "Sensors" supported by the Lithuanian State Science and Studies Foundation. RTD was performed in five directions:

• High pulse power microwave sensors
• Silicon micromachined pressure sensors and transducers
• Semiconductor gas sensors and measurement systems
• ZrO2:Y beased oxygen and carbon dioxide sensors
• Enzymes based biosensors.
