When the technology of wireless sensor network is applied to ocean monitoring, the ocean underwater monitoring system will become a distributed network system. That could improve the level of ocean monitoring significantly. But most of the current ocean monitoring equipments work independently, and it is difficult to form them into a sensor network. To set up a sensor network, electric energy s...

An electrochemiluminescence (ECL) analytical device was developed using an electric contactless power transfer system. A mutually induced electromotive voltage generated by wrapping enameled wire around a commercial charger. There no electrical contact between the supply and electrochemical cell. For tris(2,2′-bipyridine)ruthenium(II) (Ru(bpy)32+)/tri-n-propylamine system, weak ECL signal obser...

This paper presents an attractive solution to integrate multiple services in the context of sports associations. The mobile solution is tailored to youngsters and makes use of a contactless RFID chip embedded in a bracelet. It realizes a reasonable trade-off between multiple (often conflicting) requirements, namely low-cost and low-power, security, privacy and flexibility to allow for easily ad...

We introduce low-cost hardware for performing non-invasive side-channel attacks on Radio Frequency Identification Devices (RFID) and develop techniques for facilitating a correlation power analysis (CPA) in the presence of the field of an RFID reader. We practically verify the effectiveness of the developed methods by analysing the security of commercial contactless smartcards employing strong ...

Radio frequency identification (RFID) is a technology enabling a contactless exchange of data. This technology features the possibility to wirelessly transfer power to the transponder (opponent). HF-RFID is used in mobile devices like smart phones and shows potential for applications like payment, identification, etc. Unfortunately, the needed functionality increases the battery drain of the de...

Abstract Recently, wireless power transfer (WPT) technology has become a research hot spot due to its benefit of contactless transfer. Firstly, for the sake solving problem small coupling coefficient traditional orbital systems, new structure and control strategy transceiver coil was proposed, then optimal parameters system transmission efficiency were found out by comprehensive analysis LCC-S ...
