Soft wearable devices for hand rehabilitation can assist activities of daily living. While existing soft robotic gloves help with finger flexion, they are less suitable patients who cannot extend their fingers due to poststroke increased muscular tension. In this letter, we proposed a variable stiffness pneumatic actuator that effectively increases the elasticity facilitate extension. The consists fiber-reinforced and multi-stage articulated elastomer. It bends extends by actuation,...
Triphenylphosphine functionalized carbon dots (TPP-CDs) showcase robust mitochondria targeting capacity owing to their positive electrical properties. However, TPP-CDs typically involve complicated synthesis steps and time-consuming postmodification procedures. Especially, the one-step target-oriented of regulation TPP linkage modes remain challenges. Herein, we propose a free-radical-initiated random copolymerization in combination with hydrothermal carbonation regulate backbone for...
This paper presents an active islanding detection method based on injecting adaptive current disturbance according to the amplitude of voltage at point common coupling (PCC) detected after occurred reduce inverter's output current. According PCC islanding, resistance value load can be obtained. Then relationship between minimum which trigger protection and is deduced. The required adaptively added inverter voltage. As a result, power failure without non-detection zone (NDZ). IEEE Std.1547.1...
On the basis of mathematical model DFIG's Grid-Side Converter(GSC) in two-phase stationary α-β reference frame, an improved control strategy GSC is presented based on sliding-mode (SMC). The method uses double-loop structure. Direct power used inner-loop, and a sliding mode controller was designed to improve dc-link voltage stability outer-loop. has advantages simple structure, high precision, rapid response speed strong robustness, which with both excellent transient steady state behavior...
Z-source inverter can boost the voltage of DC-side, allow two switches same bridge arm conducting at time and it has some other advantages.The zero-sequence current flows through fourth leg three-phase four-leg so work with unbalanced load.This paper presents a which combines network inverter.The circuit uses simple SPWM modulation technique fully compensated control method.The maintain symmetrical output when proposed scheme under load.
In order to realize a more rigorous inverter modulation method, and improve the frequency spectrum of output harmonic so as reduce system EMI, multi-resolution wavelet (WM) technology is presented. this research, behavior modeled non-uniform recurrent sampling reconstruction process, process realized through multi resolution analysis (MRA) which constructed by basis functions combined Haar wavelet. Simulation results show that, compared with traditional SPWM inverter, spread wide relatively...
Mechanoluminescence is a kind of luminescent phenomena that produces photon emission by mechanical stimulation. Benefiting from the characteristics linear, reusable and nondestructive luminescence, it shows an attractive application prospect in field stress distribution detection attracts more attention. However, due to large size currently prepared particles, spatial resolution around 100 μm. It necessary prepare nanoscale particles. specific surface area high density defects, performance...
