Problems solved by technology

Note also that ambulatory or "at-home" monitoring of blood pressure produces ambiguous results at best and is therefore of limited use to clinicians

example 1

[0117] Example 1 - A sock incorporating combination sensors to create a dynamic CRT measurement device for the sole of the wearer's foot.

[0118] Combination sensors are incorporated into socks made of form-fitting fabric. The combination sensor monitors physiological parameters of the sole of the wearer's foot. The wearer is particularly at risk of developing diabetic foot ulcers. This is useful for diagnosing and monitoring the onset of diabetic foot ulcers. The sock may also be used in place of traditional pedobarography equipment to determine the efficacy of plantar pressure relief orthotics.

[0119] The fabric of the sock includes the fabric sensor, while the fiber optic sensor is correspondingly put into the sock. Contains coaxial configuration FOS to the Figure 13 The point shown is in contact with the wearer's foot. Each coaxial configuration FOS includes a single pair of plastic optical fibers with a diameter of 500 μm. The first sensing area is in the first ...

Abstract

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.

Description

technical field [0001] The present invention relates to sensors, especially wearable sensors, that can contact human skin and monitor clinical signs. Background technique [0002] An increasingly important area in fabric design is "smart fabrics", in which electrical signals representing physiological data are collected from clothing and transmitted to remote locations, for example for healthcare professionals to monitor, evaluate and intervene. However, because such textile devices include solid-state electronics housed in a fabric housing and worn as clothing, they are often not truly "smart" textiles. [0003] Developing fabric-based sensor systems that interact with humans or animals is challenging because the sensors need to be able to measure clinical signs and physiological parameters accurately and under the right circumstances. However, such sensors must not become cumbersome nor interfere with normal movement and activities. A significant disadvantage of most fab...
