A capsule endoscope includes a capsule portion. The fabrication process involves braiding the hinged legs on a mandrel while retaining loops of filament between the hinged leg portions for subsequent braiding of the trunk portion of the stent or graft. A fixed delay is created and maintained during modem operation. The sensor circuit is arranged for providing a probe signal and a shield signal mutually having the same phase and frequency and for generating a touch signal in response to the output signal received from the first electrode layer.
