Active Dressware: Wearable Kinesthetic Systems

Wearable, Redundant Fabric-Based Sensor Arrays for Reconstruction of Body Segment Posture

“…Elastic fabrics covered with an epitaxial layer of conducting polymer or with carbon-filled rubber show piezoresistive properties, and they can be used to realize sensorized garments, such as gloves, leotards, seat covers, and related artifacts capable of reconstructing and monitoring body shape, posture, and gesture [6]. Sensors have been realized starting from conventional fabrics coated with a thin layer of polypyrrole (PPy, a -electron conjugated conducting polymer) or by a mixture of rubber and carbon.…”

“…For the sake of simplicity again, the branches have been numbered so that the former are relative to the mesh resistors and the latter correspond to the external branches added to inject the currents. The structure of the system then becomes (6) It is interesting to note that, due to the ordering chosen, the left columns of the matrix concern the internal branches, whereas the right columns refer to the external ones. One can act the same way on the matrix (7) where the matrix is diagonal.…”

Wearable kinesthetic system for capturing and classifying upper limb gesture in post-stroke rehabilitation

“…a number of sensors bigger than the number of the degrees of freedom to of the system under consideration) distributed on a surface can provide enough information to infer the essential features concerning the posture of a subject, neglecting the precise sensor location. We borrow this approach from biological paradigms [6,7]. A theoretical approach has been tried, by searching an optimization criterion to maximize the global content of information collected by the sensor system [11].…”

“…It preserves the wearability of the ULKG and it confers to the fabric piezoresistive properties related to mechanical solicitations. This property has been exploited to realize many other sensorized garments as gloves, leotards, seat covers capable of reconstructing and monitoring body shape, posture and gesture [6]. Furthermore, by using this technology, both sensors and interconnection wires can be smeared by using the same material in a single printing and manufacturing process.…”

Analysis and Synthesis of Human Movements: Wearable Kinesthetic Interfaces

“…This work deals with the development of innovative measuring systems devoted to the human movement analysis [1], with particular emphasis to remote rehabilitation of stroke patients. In the present application, our efforts have been focused in quantifying movements by using pre-processed output signals from CEs smeared on an elastic fabric.…”
