The 66th annual Ozark Folk Festival in Eureka Springs gets underway Wednesday with the annual Barefoot Ball, 8 p.m. The show is part of the center’s Coca-Cola Night Out Series. ![]() Call (479) 443-5600 or visit the website, .Īlso at the center this week: Comedian Pat Hazell, who teamed up with Larry David and Jerry Seinfeld to write numerous episodes of NBC’s Seinfeld, will perform his one-man show, The Wonder Bread Years, a salute to baby boomers, at 8 p.m. The concert is part of the center’s 10x10 Arts Series. Friday at Fayetteville’s Walton Arts Center, 495 W. Structure with integrated rectifying circuits allows to generate the electrical output power larger than 100 mW at the rotor speed of about 8000 rpm.Austrian-based septet Mnozil Brass, who have been described as the “Monty Pythons of music” for incorporating slapstick and classic Austrian humor into their performances, will give a concert at 8 p.m. The presented electronic rectifying circuits are novel for LTCC-based electromagnetic microgenerator application. Microgenerator with Graetz bridge generates the higher value of output power than Modified Charge Pump at the same rotary speed, but is less stable for the distance change between the structure and the magnets than Modified Charge Pump, which has also more constant output power in a wider range of load resistance. In our experiment six rectifying circuits were simulated and tested with structure consisting of 8 layers of coils and with outer diameter of 50 mm fabricated earlier. The work includes research on simulation of voltage rectifying circuits, including charge pump, realization of the experimental PCB with selected electronic circuits and the execution of the final structure with integrated rectifying circuit and perform measurements on them.Įlectromagnetic microgenerators include multipole permanent magnets secured on rotor three-phase Brushless Direct Current (BLDC) motor and planar multilayer multipole coils, which were fabricated in Low Temperature Co-fired Ceramics (LTCC) technology. The paper focus on design, fabrication and characterization of electromagnetic microgenerators with integrated rectifying circuits to convert AC output signal to DC one. By boosting the output performance via continuous charge pumping, ultrahigh effective charge density was achieved successfully in flexible chitosan/BT-NR biocomposites that can push output performance towards real applications of TENGs. This work provides a promising strategy for achieving high-output, eco-friendly triboelectric nanogenerators. The TENGs demonstrate remarkable mechanical stability and reliability upon cyclical contact for up to 3,000 times. This electrical power output rises to over 4-fold more power enhancement than that of pristine chitosan TENGs. By using an integrated SCP module, the TENGs can provide a Voc, Isc and peak power output of 247.2 V, 36.7 μA/cm² and 1,568 μW/cm², respectively. Under the same testing conditions of 48 ± 5% relative humidity, ∼0.55 Hz of frequency, ∼250 N of compressive force at 25.0 ± 0.5 ☌, and the combination of 7 wt% lead-free piezoelectric BaTiO3 nanorods (BT-NRs) in the chitosan matrix, the highest open-circuit voltage (Voc) of ∼111.4 V, short circuit (Isc) of ∼21.6 μA/cm², and also output power density of 756 μW/cm² was achieved. In this work, three main strategies were proposed to enhance the output performance of chitosan-based TENGs 1) hybridization with lead-free piezoelectric nanorod, 2) introduction of a soft electrode using bacterial cellulose/carbon nanotube composite to enhance contact efficiency, and 3) enhancement of charge density of the triboelectric friction layer using a self-charge pumping (SCP) module. Boosting power generation and conversion efficiency continue to prevail. Recent advances in achieving flexible triboelectric nanogenerators (TENGs) focus widely on utilizing and modifying abundant natural biopolymer. ![]()
