A coaxially-fed single-layer single-patch wideband microstrip antenna in the form of a rectangular patch with U-shaped slot is discussed. Measurements showed that this can attain 10–40% impedance bandwidth without need adding parasitic patches another layer or same layer.
Experimental and simulation results are presented on the coaxially fed rectangular patch antenna with a U-shaped slot. include impedance bandwidth, copolar- crosspolar-pattern characteristics gain measurements. Simulation obtained mainly through development of FDTD code. It is found that U-slot foam substrate about 0.08λ thick can be designed to attain 20–30% as well bandwidths without need parasitic patches another layer or same layer. The far-field patterns have good copolar crosspolar...
A non-biological and flexible self-healing platform has tailored sensitivity toward one or a combination of pressure, strain, gas analytes, temperature. For demonstration, complete device is described in the form bendable stretchable chemiresistor, where every part self-healing.
Flexible and wearable electronic sensors are useful for the early diagnosis monitoring of an individual's health state. Sampling volatile organic compounds (VOCs) derived from human breath/skin or abrupt changes in heart-beat/breath rate should allow noninvasive disease states at stage. Nevertheless, many reported sensing devices, interaction with body leads incidentally to unavoidable scratches and/or mechanical cuts bring about malfunction these devices. We now offer proof-of-concept...
An ambipolar poly(diketopyrrolopyrrole-terthiophene)-based field-effect transistor (FET) sensitively detects xylene isomers at low ppm levels with multiple sensing features. Combined pattern-recognition algorithms, a sole FET sensor, rather than arrays of sensors, can discriminate highly similar structural from one another.
