The wireless powering efficiency of the Strongly Coupled Magnetic Resonance (SCMR) method has been reported for both homogenous and non-homogenous interfaces. Here, a new Conformal (i.e., planar) SCMR (CSCMR) method is presented that achieves high efficiency and uses significantly smaller volume than conventional SCMR. Also, the performance of traditional resonant inductive coupling, SCMR and CSCMR...
A new chipless sensor for water droplet detection is proposed. This concept is demonstrated by inkjet-printing a dual rhombic loop scatterer on a flexible substrate having a size of 4×2cm2 only. This sensor operates in the ISM band at 2.45 GHz. The scatterer is doped with a thin layer of carbon nanotube-based organic ink to enhance its sensitivity in the presence of water. Strong water molecule adsorption...
A wireless chipless sensor for structural deformation monitoring is proposed. The sensor is based on two resonant scatterers sewn on stretchable fabrics with conductive threads. The combination of the two scatterers allows for the detection of the strain in a 2-D plane. The backscattered response, as a function of frequency, is detected with the help of frequency-stepped continuous wave radar technique...
Electrocardiogram (EKG) monitoring is of prime importance in the medical world. Using the state of art technology to take it to a wireless platform can open up a broad spectrum of wireless medical devices which have a wide range of applications in medical services, military rescue missions, home cardiovascular monitoring, especially for senior people. This paper presents a platform for developing...
