IPT (inductive power transfer) charging is a highly flexible concept that allows for at any possible opportunity and versatile vehicles of all sizes. wireless technology employs high-power inductive energy transfer between the components embedded into streets receiving equipment mounted below vehicle. When vehicle moves over point, contactless process initiated In this work, role converter topo...

The direct conversion of light into work allows the driving of micron-sized motors in a contactless, controllable and continuous way. Light-to-work conversion can involve either direct transfer of optical momentum or indirect opto-thermal effects. Both strategies have been implemented using different coupling mechanisms. However, the resulting efficiencies are always very low, and high power de...

Continuous monitoring of health parameters is crucial for preterm new born babies admitted at the neonatal intensive care unit (NICU) in hospitals. The critically ill neonates are extremely tiny and vulnerable to external disturbance. In the context of ambient intelligence and smart environments, non-invasive health monitoring with wearable sensors is promising for the survival of these neonate...

As most modern cryptographic Radio Frequency Identification (RFID) devices are based on ciphers that are secure from a purely theoretical point of view, e.g., (Triple-)DES or AES, adversaries have been adopting new methods to extract secret information and cryptographic keys from contactless smartcards: Side-Channel Analysis (SCA) targets the physical implementation of a cipher and allows to re...

A microfabricated electrophoresis chip with an integrated contactless conductivity detection system is described. The new contactless conductivity microchip detector is based on placing two planar sensing aluminum film electrodes on the outer side of a poly(methyl methacrylate) (PMMA) microchip (without contacting the solution) and measuring the impedance of the solution in the separation chann...
