The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...
Contactless card payments are being introduced around the world allowing customers to use a card to pay for small purchases by simply placing the card onto the Point of Sale terminal. Contactless transactions do not require verification of the cardholder’s PIN. However our research has found the redundant verify PIN functionality is present on the most commonly issued contactless credit and deb...
Over the past decade, smartphones have become the point of convergence for many applications and services. There is a growing trend in which traditional smart-card based services like banking, transport and access control are being provisioned through smartphones. Smartphones with Near Field Communication (NFC) capability can emulate a contactless smart card; popular examples of such services i...
A new approach for the integration of dual contactless conductivity and amperometric detection with an electrophoresis microchip system is presented. The PDMS layer with the embedded channels was reversibly sealed to a thin glass substrate (400 microm), on top of which a palladium electrode had been previously fabricated enabling end-channel amperometric detection. The thin glass substrate serv...
The thermal balance analysis is a useful method to determine energy distribution and efficiency of internal combustion (IC) engines. In engines cooling concepts, estimation of heat transfer to brake power ratio, as one of the most significant performance characteristics, is highly demanded. In this paper, investigation of energy balance and derivation of specific heat rejection is carried out e...
This paper presents the theoretical analysis, simulation and design optimisation of a Series Resonant Converter (SRC) working as an interface for inductive coupling. Inductive coupling is needed when the transfer of energy has to be made without any electrical contact. In this case the coupling transformer has to be separable, i.e., the transformer parameters are time varying variables, instead...
Recent roll-outs of contactless payment infrastructures – particularly in Austria and Germany – have raised concerns about the security of contactless payment cards and Near Field Communication (NFC). There are well-known attack scenarios like relay attacks and skimming of credit card numbers. However, banks and credit card schemes often mitigate these attacks. They explain that attacks are imp...
A capacitively coupled contactless conductivity detector produced in Low Temperature Co-fired Ceramic (LTCC) technology for microchip capillary electrophoresis (CE) is reported in this work. Electrodes located outside the measurement channel are used to sense impedance variations caused by conductive ions. The application of LTCC in combination with contactless conductivity detection is very pr...
