TL;DR: In this article, an active read/write microwave tagging system using circular-polarization modulation as a novel modulation scheme for radio-frequency identification systems is presented, which reduces demodulation complexity and power consumption on the battery-powered tag.

TL;DR: In this paper, a capacitive, fibre-like stretchable strain sensor, formed of two conductors in a double helical structure, was combined with an inductive coil to create a wireless strain-sensing system for biomedical applications.

TL;DR: Sensing mechanical tissue deformation in vivo can provide detailed information on organ functionality and tissue states as mentioned in this paper, which can bridge the huge mechanical mismatch between conventional electronics and human tissue, and can be used to diagnose organ diseases.

TL;DR: In this paper, an architecture having only one directional coupler and one reflection modulator is used; the interfering signal can thus be compensated at the input of the receiver by the generation of a reflected correction signal, of which the amplitude and phase can be set by a digital signal processor (46) followed by a D/A converter (45).

TL;DR: In this paper, an impedance network using digitally tunable capacitors is proposed, where changes in the system -like antenna characteristics or cable length -can be recalibrated at any time by a controller.
