Abstract Shape memory alloy-based flexible instruments have potential for enhancing the safety in minimally invasive surgery compared to passive rigid devices. We developed a data-driven polynomial model estimate deflection of 2D bending actuator using electrical resistance. The accurately predicts deflections (mean error <3.6 mm), but force sensing augmentation is required unknown load case...

Today's medical technology makes it possible to increase leg length for people with leg length discrepancies or excessively short limbs. With the Ilizarov method bones can be gradually elongated (max. Immlday) without implantation of bone grafts or multiple operations. Although the operative procedure is relatively simple, the negative side effects for the patient are considerable. An external ...

in this research a cu-zn-al alloy is produced by melting the raw materials in an electric resistance furnace and then pouring it into a steel mould. the optimum way to achieve the final analysis in the hypo-eutectoid range is determined and the influence of the alloying element, ti on the grain size and the shape memory properties of the samples are investigated. solution treatment (done at 850...
