A photoactive tweezers system based on photoactive colloids is developed and systematically investigated in this study. Through experimental and theoretical methods, we demonstrate that the photoredox reaction catalyzed by a dye‐sensitized TiO2 particle generates a strong positive phototaxis, enabling self‐entrapment in the beam center.

Direction finding of correlated sources in extremely low SNR environment [PDF]
Direction-Finding (DF) in low Signal-to-Noise Ratio (SNR)environments presents challenges in accurate Angle-of-Arrival (AOA)estimation, resolution, and maximum detection range due to extrinsicsources and hardware imperfections, particularly when dealing ...

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the

We introduce an additively manufactured bioreactor with a perfusion flow system and integrated temperature and pH sensors for skeletal muscle tissue biofabrication. The bioreactor's performance was evaluated by assessing the viability, spreading of the myoblast cells in a printed scaffold, and contraction of the isolated murine musculi interossei ...
