Quick Abstract

The decreasing cost allows easy access and diffusion of 3D printers even for domestic use in the same way as 2D printers. The present work proposes the development of a sensorial glove in 3D printing, featuring low cost, easy reproduction and replacement. A 3D desktop printer, that was able to extrude different plastic materials, was used. In order to generate the geometric shape that best suited the hand anatomy, the 3D CAD design was based on hand photos from the top and the sagittal section. The design of the glove includes the sensor housings, which are pockets within which the sensor can slide during joint bending. The wiring of 10 flex sensor and the acquisition board designed for a Lycra glove were easily applied to the printed glove without modification. The glove in 3D printing was able to control virtual or mechanical hands, which provides for surgical, military, space and civil applications. The possibility to achieve waterproofing allows the use in applications that require contact with solvents or water. A standard test applied to six healthy subjects demonstrated that the proposed glove achieves performances, in terms of repeatability, reproducibility and reliability, comparable to that of the other literature gloves.

Quick Abstract

Recent studies have found that in normal human walking the stance and swing phases are approximately in proportion to , the golden ratio. This could provide an interesting tool in human gait analysis, in diagnosing pathological conditions or in analysing the walking performance of a subject. However, the assessment of gait harmony was provided in previous studies by means of optical systems, which are not ideal for clinicians, because of non-portability, high-costs, and necessity of expert supervisor skills. In addition, the assessment regarded mostly middle-aged or aged people. Differently, this work is based on wearable technology to sense human walking, and reports a comparison between elder and young people. Results demonstrate how elders adopt a walking style which better minimizes the energy expenditure.
