Field Emission Pattern Image of Carbon Nanotubes has been captured by using electron beam scanning analyzer. The measurement showed that the Faraday cup scanning method can provide a high resolution field emission sites distribution measurement (the best resolution is up to 0.01mm), which is higher than that using the transparent anode method.
A hermetic neurostimulator is being developed to restore functional sight to the blind. The latest developments are presented on the Boston 256-channel retinal prosthesis. The device includes a hermetic package made of titanium and alumina, containing an integrated circuit chip with 256 independently addressable current drivers. The prosthesis attaches to the outside scleral wall of the eye and electrically...
A small, hermetic, wirelessly-controlled retinal prosthesis was developed for pre-clinical studies in Yucatan mini-pigs. The device was implanted on the outside of the eye in the orbit, and it received both power and data wirelessly from external sources. The prosthesis drove a sub-retinal thin-film array of sputtered iridium oxide stimulating electrodes. The implanted device included a hermetic titanium...

The measuring of elastic modulus based on ultrasonic is the key to improve the propagation time measurement accuracy. In addition to the use of advanced equipment and software algorithms, the error of measurement time caused by the acoustic coupler interface can be completely avoided by use of step-axis specimen. Using time interval between primary and secondary pulses can effectively eliminate the...
PCASP-X2 is a ground-base aerosols instrument with high time resolution reach up to 1s, a short-term observation for testing its performance of detecting the number concentration of aerosol particles with another instrument WPS™ was carried out in November 2009 in Nanjing University of Information Science and Technology (NUIST). The data were analyzed by using the meteorological parameters which were...
A miniaturized, hermetically-encased, wirelessly-operated retinal prosthesis has been developed for pre-clinical studies in Yucatan minipig animal models. The prosthesis attaches conformally to the outside of the eye and drives a microfabricated thin-film polyimide stimulating electrode array with sputtered iridium oxide electrodes. This array is implanted in the subretinal space using a specially-designed...
