... the creation of devices that minimize adverse outcomes. The current modeling techniques (e.g., animal models, in vitro testing, and finite element analysis) used to analyze these effects are costly and are not readily accessible to the clinician. It is proposed that the pseudo-rigid-body model(PRBM...

... by passive means, the cost and weight associated with individual sensors, valves, and/or actuators are essentially eliminated. This paper presents the design, analysis, fabrication, and experimental results of an array of such self-sealing suction cups. Finite element analysis of the cup is shown for...
