Abstract

The invention refers to a sensor arrangement comprising at least one capacitance sensor for detecting a pressure and a shear force, wherein the capacitance sensor is integrated into a wearable textile, a method for measuring a shear force and a pressure by such a sensor arrangement, wherein the shear force and pressure is exerted on a skin of a person lying in a bed or sitting in a chair and to combinations and uses of the method. This described textile sensors allow for a simultaneous measurement of shear stress and pressure in anti decubitus textiles. This enhances risk assessment with regard to the development of bedsore ulcer.

Description

technical field [0001] The invention relates to a sensor arrangement comprising at least one capacitive sensor for detecting pressure and shear force, wherein said capacitive sensor is integrated into a wearable fabric; a sensor arrangement for measuring shear force and A method of pressure, wherein said shear and pressure are applied to the skin of a person lying in bed or sitting in a chair; and combinations and uses of said methods. Background technique [0002] Measuring pressure or pressure distribution in bed is known in the art. One application that is very important is the monitoring of patients at risk of developing decubitus ulcers (also known as pressure ulcers or pressure sores) or injuries anywhere in the body, especially in areas of bone or over cartilage areas. people. The cause of these bedsores is a combination of various external factors such as pressure, friction, shear force, and moisture, and internal factors such as fever, malnutrition, anemia, and en...
