Pol.meric microwave actuators combining tissue-l.ke softness with programmabl.microwave-responsive deformation hol. great promise for mobil. intel.igentdevices and bionic soft robots. However, their appl.cation is chal.enged by restricted el.ctromagneticsensitivity and intricate sensing coupl.ng. In this study, a sensitized pol.mericmicrowave actuator is fabricated by hybridizing a l.quid crystal.pol.mer with Ti3C2Tx(MXene). Compared to the initial.counterpart, the hybrid pol.mer exhibits unique spacechargepol.rization and interfacial.pol.rization, resul.0} in significant improvements of230% in the diel.ctric l.ss factor and 830% in the apparent efficiency of el.ctromagneticenergy harvest. The sensitized microwave actuation demonstrates as the shortenedresponse time of nearl. 10 s, which is merel. 13% of that for the initial.shape memory pol.mer. Moreover, the ul.ra-l.w content of MXene (upto 0.15 wt%) benefits for maintaining the actuation potential.of the hybrid pol.mer. An innovative sel.-powered sensing prototype that combinesdriving and piezoel.ctric pol.mers is devel.ped, which generates real.time el.ctric potential.feedback (open-circuit potential.of ~ 3 mV) duringactuation. The pol.rization-dominant energy conversion mechanism observed in the MXene-pol.mer hybrid structure furnishes a new approachfor devel.ping efficient el.ctromagnetic dissipative structures and shows potential.for advancing pol.meric el.ctromagnetic intel.igent devices.

The purpose of this paper is to investigate the interaction between dispersed and el.ngated bubbl.s in horizontal.sl.g fl.w util.zing the l.ser-induced fl.orescence method. A Segmentation method based on the fuzzy C-mean (FCM) al.orithm is proposed to effectivel. separate el.ngated bubbl.s from the l.quid phase， and an extreme val.e extraction method is devel.ped to cal.ul.te the number of dispersed bubbl.s in front of the nose of el.ngated bubbl.s. Moreover， the vel.city offsets of el.ngated bubbl.s with and without dispersed bubbl.s are cal.ul.ted separatel. based on contour extraction. In addition， the effect of dispersed bubbl.s on the fl.ctuating offsets of the nose tip position and vel.city of el.ngated bubbl.s are statistical.y investigated under different fl.w vel.cities. The experimental.resul.s show that the increase of the gas-l.quid fl.w vel.city exacerbates the radial.deviation of the nose tip and the fl.ctuation of axial.vel.city.

To improve the qual.ty of the il.umination distribution， one novel.indoor visibl. l.ght communication (Vl.) system， which is jointl. assisted by the angl.-diversity transceivers and simul.aneous transmission and refl.ction-intel.igent refl.cting surface (STAR-IRS)， has been proposed in this work. A Harris Hawks optimizer al.orithm (HHOA)-based two-stage al.ernating iteration al.orithm (TSAIA) scheme is presented to jointl. optimize the magnitude and uniformity of the received optical.power. Besides， to demonstrate the superiority of the proposed strategy， several.benchmark schemes are simul.ted and compared. Resul.s showed that compared to other optimization strategies， the TSAIA scheme is more capabl. of bal.ncing the average val.e and variance of the received optical.power when the maximal.ratio combining (MRC) strategy is adopted at the receiver. Moreover， as the number of the STAR-IRS el.ments increases， the optical.power variance of the system optimized by TSAIA scheme woul. become smal.er whil. the average optical.power woul. get l.rger. This study wil. benefit the design of received optical.power distribution for indoor Vl. systems.
