A Novel Single-Feed Circular Microstrip Antenna With Reconfigurable Polarization Capability

Abstract: A single-feed circular microstrip antenna with reconfigurable polarization capability is proposed. This antenna has a simple structure, which consists of a radiating circular patch, five switches (PIN diode), three matching stubs, and a 50 microstrip feed line. It can be switched between 4 different states: two states (low-frequency and high-frequency) for linear polarization (LP), one state for left hand circular polarization (LHCP) and one for right hand circular polarization (RHCP) by controlling the bias voltage of two PIN diodes. At the same time, three switchable matching stubs are used for matching every polarization state. Simulation results and experimental results show that the proposed antenna demonstrates a low cross polarization level, good impedance bandwidth, and a very good axial ratio in the circularly polarized states.

Abstract: A contactless power charging system and an energy storage system including the same, the contactless power charging system including a contactless transformer configured to transmit power stored in a battery to a load, wherein the contactless transformer includes a primary core unit, the primary core unit including a first base portion, a projecting portion projecting from the first base portion, and a primary coil wound around the projecting portion; and a secondary core unit, the secondary core unit including a second base portion, a concave portion in the second base portion to receive the projecting portion, and a secondary coil on an inner surface of the concave portion, the secondary coil being configured to couple to the primary coil.

Super-Flexible Nanogenerator for Energy Harvesting from Gentle Wind and as an Active Deformation Sensor

Abstract: Using an Al-foil of thickness ≈18 μm as a substrate and electrode, a piezoelectric nanogenerator (NG) that is super-flexible in responding to the wavy motion of a very light wind is fabricated using ZnO nanowire arrays. The NG is used to harvest the energy from a waving flag, demonstrating its high flexibility and excellent conformability to be integrated into fabric. The NG is applied to detect the wrinkling of a human face, showing its capability to serve as an active deformation sensor that needs no extra power supply. This strategy may provide a highly promising platform as energy harvesting devices and self-powered sensors for practical use wherever movement is available.
