Microelectromechanical systems (MEMS), also called accelerometers, are widely used for diverse applications in the field of electronics, sports and defense. Researchers at Tel Aviv University are molding these miniature MEMS sensors to make them tiny, cost-effective and precise by blending conventional mechanics with hi-tech electrical engineering.
According to Dr. Slava Krylov, Tel Aviv University's Engineering Faculty, the influence of MEMS on the common systems revolutionizes the world. He has published a paper along with his student Assaf Ya'akobovitz in IEEE Sensors Journal on the methods of enhancing the flexibility of MEMS by employing an effective, lucid, fabricative design for applications in transport, communication, defense and sports.
The researchers could prove the efficiency of microsensors using amplification tools devised in their laboratory. They opted the mechanical amplification method to create stronger signals, weakening the noise and enhancing the sensitivity of the device. Dr. Krylov commented that the advancements in the sensitivity aspects of the micro sensors will make them applicable in productive as well as developing business establishments.
The MEMS design includes a silicon chip, miniature electrode, and a transformer combined with an optical sensing device to intensify the minute differences in the movements and speed. The device has a diameter of about 1mm and can be made even minute in the coming years.
Dr. Krylov points out that the device is so precise that it can be used in space explorations, where accurate space and time is exploited for satellite missions. In addition Dr. Krylov plans to expand this miniature technology in the field of medicine and environment protection in the near future.
