Geophysicists are familiar with physical magnetometers that sense the Earth’s geomagnetic field, but there also other sensors of field which biological. For at least pas...

a bearingless induction machine has combined characteristics of induction motor and magnetic bearings. therefore, the advantages are small size and low-cost. in the magnetic suspension of the bearingless motors, suspension forces are generated based on the feedback signals of displacement sensors detecting the movement of the rotor shaft. the suspension forces are generated taking an advantage ...

biosensors are classes of sensors in which at least a biological process is used in sensing procedure. they are generally composed of three parts: a sensing element, a transducer, and a signal processor (or detector). they can be categorized by type of sensing materials or by detection techniques. from their invention time up to now, various biological species have been analyzed using variety o...

One dimensional polyaniline nanowire is an electrically conducting polymer that can be used as an active layer for sensors whose conductivity change can be used to detect chemical or biological species. In this review, the basic properties of polyaniline nanowires including chemical structures, redox chemistry, and method of synthesis are discussed. A comprehensive literature survey on chemires...
