In this work, the photolithography processed nickel (Ni) grids were used to replace indium tin oxide (ITO) as the transparent anode for perovskite solar cells. The results show that the Ni grids have a senior adhesion ability to glass substrates than that of Ag grids, and the obtained device show a comparable short circuit current density (JSC) to that of ITO based device, while the open circuit voltage...
Human pulse replication is an emerging technology that enables telediagnosis in traditional Chinese medicine. However, soft actuation with multi-frequency tracking capability is in great need for replicating human pulse signal. Dielectric elastomer (DE) is one type of soft actuating materials, which shows great potential in human pulse replication. In this paper, we developed a model-based robust...
A novel depth control device has been designed and built. The proof-of-concept device utilizes the principles of electrolysis of water, enhanced by the inclusion of an ionic polymer-metal composite (IPMC) membrane as a medium. The device design incorporates an artificial bladder where the volume of gas generated by electrolysis is controlled by a solenoid valve, thus changing the device's buoyancy...
The structural characteristics of one kind of the capacitor vortex flowmeter was introduced for raising up its survey performance. According to elaborately expounding the vortex survey theory, the mathematical relation between the variations of vortex force and capacitor was studied. The mathematical model of vortex flow survey was established and simulated and the simulated results were carefully...
