The present invention relates to a smart textile garment, a system and a method for functional assessment and monitoring of the lumbar spine, based on the acquisition of bioelectrical signals and data concerning a user's postures and movements, which, in combination with artificial intelligence techniques, allows the sensations perceived by the user to be objectively assessed and classified, eliminating the subjective component in this operation. For this purpose, the garment of the invention incorporates a plurality of textile electrodes for acquiring various bioelectrical signals, such as ECG (HRV), EMG and / or EDA, which are processed by control electronics linked to a movement and posture acquisition system and to processing software that uses machine learning methods to associate patterns of movement and posture with bioelectrical signals indicative of injuries causing lumbar pain.

An apparel system integrates a physiology-sensing inner sleeve within conventional garments to conceal hardware while maintaining natural arm mobility. A sensing sleeve with a sensing armhole opening is secured at a garment armhole region with substantially corresponding circumferences and may be sewn, bonded, or removably coupled. A sensor assembly comprising a sensor panel and / or textile electrodes contacts the wearer's skin to acquire physiological signals, such as photoplethysmogram, electrocardiogram (single- or multi-channel), and ballistocardiogram data, which are delivered to a computing device via conductive fibers. A conductive textile interconnect routed through a yoke, shoulder seam, collar, side seam, or body panel couples the sensing sleeve to a complementary sleeve on the opposite arm. Assembly methods include coupling sleeves at their armhole openings, attaching the sleeve unit to a garment body, and integrating the sensor assembly and interconnect for use across a variety of garments.

The present invention relates to a method for obtaining a textile electrode embroidered on a textile substrate and to the electrode obtained using the method, which, advantageously, enables signal acquisition by means of same with improved quality and amplitude. For this purpose, the method of the invention comprises two steps of embroidering with a conductive thread, with an intermediate step of placing a piece of foam, such that the stitches of each step of embroidering have different orientations, producing an electrode with a three-dimensional structure, which ensures continuous contact and adequate pressure against the surface from which the signal is to be obtained, ensuring optimal signal quality and amplitude for same.

Functional electrical stimulation devices and methods of operating the same are described. For example, a device includes a high-efficiency power boost circuit configured to step a low battery voltage to a boosted output voltage, an open-loop charge pump circuit coupled to the power boost circuit to further increase the boosted voltage, and a switched capacitor output stage to generate high-slew-rate, charge-balanced stimulation pulses. The switched capacitor stage may produce symmetric or asymmetric bi-phasic pulses with adjustable amplitudes, widths, and frequencies over an operating range. The boost and charge pump stages may operate in discontinuous conduction and discontinuous voltage modes to achieve soft switching and improved efficiency at high conversion ratios. The devices may be incorporated into wearable electrical stimulators using textile electrodes. Methods are also provided for operating the power boost circuit, the charge pump circuit, and the switched capacitor stage to deliver controlled stimulation to electrically excitable tissue.

Textile garments comprising integrated textile electrodes and methods of producing the same are disclosed. The garments include a non-conductive spacer-knit border that circumscribes the perimeter of a textile electrode to mechanically isolate the electrode from surrounding portions of a flat-knitted base fabric. In certain embodiments, the electrode and border incorporate a melting copolymer yarn, such as a polyamide-based hot-melt yarn, selectively integrated within structural knit layers and activated by steaming to bond adjacent fibers and increase local stiffness relative to the base knit. The architecture reduces elongation of the electrode region during garment stretch, improves stability at the skin interface, and enhances bio-signal acquisition without adhesives, while maintaining garment comfort and washability.
