Welcome to suzuki laboratory! ----------------------------------------------------------- Our laboratory works for the research and development of wireless and optical components based on Microelectromechanical Systems (MEMS). The resulting researches are expected to open up entirely-new research fields that fuse the electromagnetic microwaves with mechanical vibrations. We hope that the obtained researches are adopted for the advanced wireless communications and sensing systems, which will help to construct the infrastructure for next generation ubiquitous network. |

Our researches ----------------------------------------------------------- We are now under research for future Radio Frequency MEMS (RF-MEMS) devices and sensors: millimeter-wave radar, MEMS resonator, MEMS filter, and gyroscope. The millimeter-wave radar Millimeter-wave is an electromagnetic wave with the frequency range of 30-300 GHz. The millimeter-wave has several advantages over lower frequency waves: 1) very high directionality, 2) transmitting a huge of information at once, and 3) little fading due to water drops (mist) in the distance of about 100 m. These features make the millimeter-waves to be adapted for use in portable wireless communications, radars of collision protection and more [1]. In our laboratory, the millimeter-wave radar, small and low consumption power, comprised of RF-MEMS switches, phase shifters, and antennae is under research. More detail(pdf） MEMS resonator In present days, a lot of resonators are used in mobile phones, oscillators and filters, which are commonly made of crystal. However, they become very difficult to satisfy with the demands from the rapid progress in social and commercial apparatuses; higher frequency (over UHF) and wider bands. MEMS resonators are expected to satisfy these demands. More detail(pdf) MEMS filter With the development of information terminal devices, there exists a growing demand on high performance variable filters for use in multi-function, multi-band wireless systems. In order to realize multi-band pass filters in multi-band frequencies, our laboratory works for research and development of MEMS filters based on a unique priciple. More detail(pdf) The gyro scope Gyroscope is an angular velocity sensor, which is widely used in an airplane, artificial satellite, car navigation system, digital camera, and video game’s controller. Our laboratory researches for improving the performance of a vibration-type MEMS gyroscope. The vibration-type MEMS gyroscopes are small in size and can be fabricated in an affordable price. However, the improvement of sensitivity is strongly required. We research to improve the sensitivity in the vibration-type MEMS gyroscopes.. more detail(pdf) Reference |
