Demonstration of the hexagon balloon in a full condition and its star-like shape in an empty condition. Its folds facilitate the complete closure of the balloon and leads to nearly zero internal volume in the empty configuration.

Demonstration of the flexible braided links that intersect to form a variable diameter cylinder. This can transfer the actuation compression force to the balloon and fold the balloon's sides to create a star-like shape. Moreover, it works as a base structure to hold sensors. We experimentally measured the inductance changes while the springs were in cyclic elongations by a linear stage actuator.

Demonstration of the bench top trials on bladder volume estimation and assisted micturition. Trials were initiated in an empty state and by dynamic actuation, the cables tension was adjusted in real time to avoid extra high or low radial forces on the bladder body. The trials have been ended with a voiding phase by opening the valve and activating the cable-based actuation mechanism.
