This work focuses on measuring precise values of passive elements such resistors, inductors and capacitors through non-contact means through inductive coupling for series and parallel. Resonant circuit is used for selective identification of high frequency components. However, if one of the circuit components such as the inductance, capacitance or resistance is made to vary, it will cause a change...
This paper presents the categorization of magnetic and non-magnetic materials across a low frequency band through conducting a non-contact measurement of a passive resistive element for low frequency applications. Three different materials have been used as core for the coupled coils. The experimental results for the test circuit with inductive and resistive load separately are obtained under different...
This work is about modeling a readout system across narrow gaps using inductive means for a contact-less transfer of signal. The signal source could be devices implanted in humans or animals or even devices embedded buried in inaccessible locations for monitoring purposes, while the readout devices are normally in accessible locations in the external world. This work focuses on modeling the coupled...
Powering implantable low wattage biomedical devices and sensors through non-contact means is on the rise over the past recent years. In view of that, inductive coupling is currently the most favorable means of transferring energy for powering the low wattage implanted devices. The wireless inductive link works as an energy link to power up remote devices and also acts as a communication link to retrieve...
This paper presents the design of a passive RFID tag antenna operating at 2.45 GHz. The electromagnetic simulation software called CST is used for design and simulation. A high gain (5.842dB), a good impedance matching with the microchip (−30.0 dB Return Loss) and a satisfactory read range performance (upto 5 m) was obtained. One approach of designing RFID tag is that the tag should be less sensitive...
Transducers and sensors play an important role in instrumentation and measurement. Expectations from non-contact biomedical implants are getting renewed interests among researchers. A novel work is carried by presenting a non-contact technique as an inductive transducer coils. A theoretical analysis of an inductive transducer is given which is followed by a development of non-contact measurement technique...
