A piezoresistive sensor for micro-grippers, capable of detecting the contact position of the micro-object along the vertical dimension of the grasping surface as well as the grasping force, has been developed and successfully tested. The integration of this sensor into micro-grippers would improve their reliability because the monitoring of the grasping position is fundamental in many micro-assembly...
A convection based multi-axis tilt sensor using air medium has many advantages, such as small size, simple structure, low cost, reliability and durability. In this paper, a study focused on optimizing two different parameters, the geometry of temperature sensors and air volume of encapsulated micro-chamber filled with air medium, is mainly reported.
Paper reports morphological and humidity sensing application of Cu2O doped ZnO composite prepared by solid state reaction. Pellet samples of ZnO-Cu2O nanocrystalline powders with 5, 10, 15 and 20 weight % of Cu2O in ZnO have been prepared. These pellets have been annealed at temperatures 200-500??C. When samples have been exposed to humidity, it has been observed that as relative humidity increases,...
Strain gauges based on multi-walled carbon nanotubes (MWCNTs) realize a higher sensitivity and a larger operation range than usual metallic strain gauges. Different technologies for CNT-layers have been realized. With the aim to find a suitable technology that allows the application of CNT strain gauges without use of adhesives. For this purpose two detergents (SDS: Sodium Dodecyl Sulfate and DOC:...
In this paper the response of printed thick-film of WO3 doped by Y2O3 to organic solvent was studied. Different ratio of doping was prepared and changes of film resistance at different temperature in present of vaporized types of alcohol were observed. The results showed a high sensitivity of the film of 80.1%WO3-18.8%Y2O3 to Toluene, Xylene, Methanol, and 2-Propanone (Acetone) at 250, 450, and 550degC,...
Summary form only given. Key issues for distributed generation (DG) inclusion in a distribution system include operation, control, protection, harmonics, and transients. This paper analyses two of the main issues: operation and control for DG installation. Inclusion of DG in distribution networks has the potential to adversely affect the control of voltage. Both DG and tap changers aim to improve...
