Textile-integrated module for recording ECG signals, heat flow, blood flow and tissue vibrations

Abstract

Sensor system for the combined detection of ECG signals, heat flow, blood flow and tissue vibrations, characterized in that the sensors operate capacitively, thermally and / or mechanically and are fixed or modularly incorporated in the textile.

Description

2. Technical area

[0001] The invention relates to the field of wearable medical technology, in particular textile-integrated sensors for recording cardiac parameters (planned under the name AIDEM.pulse). 3. State of the art

[0002] To date, modules exist that can detect individual vital parameters such as electrocardiographically displayed heart rate or temperature. However, there is a lack of modular, fabric-integrated solutions that allow combined and precise recording of multiple parameters such as heart rate, heat flow, blood flow, or tissue vibrations, while being comfortable to wear in everyday life. 4. Object of the invention

[0003] It is the object of the invention to provide a modular or fully textile-integrated system that is housed in a garment or wearable textile module and enables combined measurement of electrocardiographic heart actions, heat flow, blood flow and tissue vibrations. 5. Description of the invention

[0004] The invention comprises a sensor system that can simultaneously record multiple physiological parameters. The module consists of conductive fibers or sensory fabric structures that can record capacitive and thermal signals. The sensors are either permanently woven into the textile or can be positioned modularly at specific body locations.

[0005] The system contains electrical contact points for signal acquisition, a microcontroller for data preprocessing, and a data transmission unit that communicates either wirelessly or via textile conductors. Positioning is preferably in the chest area, but can also be done at other locations. 6. Example

[0006] One example consists of a textile module in the form of an elastic chest band that fits close to the skin. Conductive fibers are integrated into this band to record ECG signals, while thermosensitive elements along defined paths register heat flow. Infrared or microsensor technologies can also be used to detect blood flow and micro-oscillations. The signals are processed in a compact module and transmitted via Bluetooth to an evaluation unit.
