A method for making a textile sensor and a textile sensor can include selecting a combination of variables from the group consisting of yarn variables, stitch variables, and textile variables; and knitting an electrically conductive yarn in the textile sensor in accordance with the selected combination of variables, wherein the combination of variables is selected so as to provide a controlled amount of contact resistance in the textile sensor. The method and textile can further include a capacitive textile-sensor having at least two integrally knit capacitor plate elements and having a configuration adapted for a sensing activity. Resistance in the textile sensor can automatically calibrate to a stable baseline level after the textile sensor is applied to a body.

An independent wearable health monitoring system is configured for use by a living being on a daily basis. The system includes a knitted garment worn by the living being adjacently to preconfigured body locations, a garment-processing device having processor, and a multiplicity of sensors adapted to measure health parameters, wherein at least some sensors are integrally knitted with the knitted garment, and wherein the knitted textile sensors include electrodes adapted to provide ECG data. The system further includes an interface adapted to operatively connect at least one external medical device to the garment-processing device. Preferably, the health monitoring system further includes two conductive, integrally knitted pads operatively disposed tightly adjacently to the skin of the monitored living being, adapted to facilitate placing of a respective defibrillator paddles thereon and applying defibrillator shocks. Preferably, the garment-processing device controls the activation and deactivation of the defibrillator shocks.

A combined sensor adapted to measure at least one medical or clinical sign is provided. The combined sensor comprises a textile sensor configured so as to determine pressure applied to the combined sensor; and an optical sensor. The optical sensor typically comprises at least one fibre- optic sensor (FOS) and may function as a photoplethysmography (PPG) sensor, optionally a reflectance mode photoplethysmography (PPG) sensor. The combined sensor is able to eliminate motion artefacts caused by movement of a subject wearing the sensor thereby facilitating long-term ambulatory monitoring of subjects.

The invention provides a method for manufacturing a textile temperature sensor (100). The method comprises the steps of arranging a linear knitting machine comprising at least one first thread-guide and a second thread-guide; arranging a conductive insulated wire (120) on the first thread-guide, said conductive insulated wire (120) having a first end (121) and a second end (122); meshing the conductive insulated wire (120) for making a mesh portion B having not conductive surface.

A process for the large-scale manufacturing vertically standing hybrid nanometer scale structures of different geometries including fractal architecture of nanostructure within a nano / micro structures made of flexible materials, on a flexible substrate including textiles is disclosed. The structures increase the surface area of the substrate. The structures maybe coated with materials that are sensitive to various physical parameters or chemicals such as but not limited to humidity, pressure, atmospheric pressure, and electromagnetic signals originating from biological or non-biological sources, volatile gases and pH. The increased surface area achieved through the disclosed process is intended to improve the sensitivity of the sensors formed by coating of the structure and substrate with a material which can be used to sense physical parameters and chemicals as listed previously. An embodiment with the structures on a textile substrate coated with a conductive, malleable and bio-compatible sensing material for use as a biopotential measurement electrode is provided.

The present application describes the creation of a flexible textile structure with sensing and lighting capabilities without the loss of important features of a typical textile, for instance, comfort, seamless and mechanical flexibility. As sensing applications are described three different approaches that may or may not work together in the same system: a directly printed self-capacitive sensor, a knitted textile sensor and the integration of temperature / humidity bulk capacitive sensors directly on the textile. As lighting applications for decorative and signage purposes are used two different approaches that could work individually or together: an electroluminescent sensing device and the use of a hybrid sensor that includes the use of SMD LEDs and a printed self-capacitive sensor. The sensing and lighting applications previously described can be used, as an example, inside an automobile passenger compartment since they are easily integrated on seats with different geometries, armrests and central panels to substitute common mechanical buttons and sensing devices, and create a cleaner and seamless environment, following current tendencies in car interiors.

The invention discloses a method and a device for testing the infrared emission difference between the front and back of textiles. The test device includes: a bracket part, a horizontal movement part, a test part composed of an infrared light source, an upper and lower measuring arm and a sensor. The method of testing the infrared emission difference between the front and back of the textile is: fix the sample to be tested on the test board, turn on the infrared light source, realize the left and right movement of the test board through the horizontal movement part, transport the textile to the test position, and pass the upper and lower measuring arms. The sensor is used to measure the dynamic change of the infrared radiation intensity on the front and back of the textile from entering the infrared radiation area to the steady state. Through the data measured by the sensor, the direct infrared radiation intensity of the front and back sides, the infrared intensity emitted by the front and back sides, and the difference between the infrared emission intensity of the front and back sides are obtained, which can be used in the textile testing industry to realize the infrared emission of the front and back sides of textiles. A quick measure of difference.
