We developed selective and rapid injection of fluorescence sensor into the cell for intracellular measurement. The sensor encapsulated in the liposome contains photochromic chemical, 1, 3, 3-Trimethylindolino-6'- nitrobenzopyrylospiran, for optical control of zeta potential. The molecular structure of spiropyran changes between spiropyran type and merocyanine type by UV/VIS illumination. Zeta potential...
Multi-fluorescent sensor has been synthetized using two different fluorescent indicators (Rhodamine B and FITC) which can respond to both pH and temperature. A method of selective adhesion and rapid injection of the sensor into the individual cell have also been proposed. The sensor was encapsulated in the liposome layers containing photochromic material, 1, 3, 3-Trimethylindolino-6'- nitrobenzopyrylospiran...
The present study describes the MEMS-based piezoelectric switch to activate the event-driven wireless sensor node for chicken health monitoring system. We have fabricated the switch composed of “S” shaped piezoelectric cantilever and proof mass, where the resonance is 24 Hz. When the switch has been vibrated at 4, 6, 8, and 12 Hz, which is close to the chicken movement frequency, the input vibration...
Here, we propose a practical single pole double throw (SPDT)-structured radio frequency microelectromechanical system (RF MEMS) switch for RF applications. This SPDT switch has a very low insertion loss of 1.0 dB and a high isolation of 40 dB, up to 10 GHz. The fabricated switch is compact in size (5.2times3.0times1.8 mm3) with a Land Grid Array Package. The research and development of an RF MEMS...
