— A novel wireless and passive temperature sensor that utilizes microfluidic and liquid metal technologies for the temperature-dependent modification of the sensor's radar echo is introduced. Liquid metal is used to dynamically alter the number of antenna elements activated along a linear array configuration with respect to temperature. In this way, the(More)
— A novel design of a highly sensitive wireless passive radio frequency strain transducer is presented based on a patch antenna loaded with an open loop that is capable of sensing strain remotely. The new idea of utilizing a cantilever at the gap of the open loop significantly improves the sensitivity of resonant frequency shifts. In measurements, the(More)
— A highly sensitive wireless passive radio frequency strain transducer is designed and developed based on a patch antenna loaded with an open loop. A novel idea of utilizing a cantilever at the gap of the open loop significantly improves the sensitivity of resonant frequency shifts. The ground plane allows the sensitivity of the sensor to be independent(More)
—An RCS temperature sensor using microfluidics technology for millimeter-wave frequencies is presented An example using a shorting dipole array shows the potential for the development of a temperature sensitive liquid scatterer as a low cost solution for environmentally friendly, automated, easily deployable temperature monitoring. I. INTRODUCTION A new(More)
— A wireless, passive, and ultrasensitive temperature transducer is presented in this paper. The transducer consists of split ring resonators loaded with micro-bimorph cantilevers, which can potentially operate up to millimeter-wave frequencies (above 30 GHz). As the temperature changes, the bimorph cantilevers deflect and result in a shift of the resonant(More)
The development of a new passive wireless pressure sensor, based on an electromagnetic trans-duction approach, is reported. The sensing element is a flexible high resistivity silicon membrane located above a coplanar quarter-wavelength resonator. The comprehensive coverage of the physical bases is beyond the scope of this paper. For the remote extraction of(More)
—The concept of Scale-Changing Network is reported for the electromagnetic modeling of complex planar structures composed of a collection of metallic patterns printed on a dielectric surface and whose size covers a large range of scale. Examples of such multi-scale structures are provided by multi-band frequency-selective surfaces, finite-size arrays of(More)
