Wireless power transfer (WPT) is one solution to realize long flight times and accommodate various missions of micro-uncrewed\naerial vehicles (MAVs). Reducing the constraint of power transmission distance and realizing high beam efficiency are possible\nbecause of the high directivity of WPTusing millimeter wave (MMW) methods. Nevertheless, no report of the relevant literature\ndescribes an investigation of sending power to an MAVusingMMWbecauseMMWrectennas have low efficiency. The purpose of\nour study is to conduct fundamental research of a high-efficiency and high-power rectenna at 94 GHz aimed at MAV application\nusing MMW.............................
In this study, the effects of capping layers with different metals on the electrical performance\nand stability of p-channel SnO thin-film transistors (TFTs) were examined. Ni- or Pt-capped SnO\nTFTs exhibit a higher.................
This paper presents the design and testing of a low-noise programmable voltage source.\nSuch a piece of instrumentation is often required as part of the measurement setup needed to test\nelectronic devices without introducing noise from the power supply (such as photodetectors, resistors\nor transistors). Although its construction is based on known configurations, here the discussion\nis focused on the characterization and the minimization of the output noise, especially at very\nlow frequencies. The design relies on a digital-to-analog converter, proper lowpass filters, and a\nlow-noise Junction Field-Effect Transistors (JFET) based voltage follower....
High-performance n-type organic semiconducting polymers are key components of\nnext-generation organic electronics. Here, we designed and synthesized two electron deficient\norganic polymers composed of benzodifurandione-based oligo (p-phenylenevinylene) (BDOPV)\nand benzothiadiazole by Stille coupling polycondensation. BDOPV-benzothiadiazole-based\ncopolymer (PBDOPV-BTT) possesses a D-A1-D-A2 type backbone with intramolecular chargeâ??transfer\ninteractions, while PBDOPV-BTTz is an all-acceptor polymer....
We introduce fluoride-selective anion exchange resin sorbents as sensitisers into membranes\nfor water-gated field effect transistors (WGTFTs). Sorbents were prepared via metal (La or Al)-loading\nof a commercial macroporous aminophosphonic acid resin, PurometTM MTS9501, and were filled into a\nplasticised poly(vinyl chloride) (PVC) phase transfer membrane...................
