As the process before transporting of capsule in a hydraulic pipeline system, capsule’s threshold motion is often tested horizontal straight pipe. However, result physical test this work shows that wheeled more easily start-moves bent Thus, numerical simulation and theory analysis were used to study The results demonstrate velocity magnitude water flow was asymmetric between inner part outer se...

This paper presents a conformal spiral antenna that is miniaturized and with dual-resonant for the wireless implantable capsule system. The conforms to swallowable radius of 3 mm length 26 without occupying internal space capsule. compact adopts two arms extend effective current path miniaturization. Biocompatible flexible polyimide was used as dielectric substrate shell, achieving properties w...
