Arrangement for performing contactless detection of moisture in e.g. commercial diaper, has oscillating circuit directly stitched on or into incontinence material that is releasably arranged on or in support material

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention is a contactless moisture detection system, mainly designed for use in products like commercial diapers or incontinence pads. It uses an oscillating circuit made from conductive thread, which is stitched directly onto or into the absorbent material. This circuit operates as a resonance sensor to detect moisture levels and is powered wirelessly.

Use CasesContent extracted from patent full text and abstract with AI.

• Monitoring moisture levels in baby or adult diapers to indicate when a change is needed
• Integrating into hospital bedding or incontinence pads for better patient care
• Detecting wetness in medical textiles without direct electrical connections

BenefitsContent extracted from patent full text and abstract with AI.

• Enables early detection of moisture for improved hygiene and patient comfort
• The sensor can be easily integrated into absorbent materials without affecting comfort or usability
• Contactless and wireless design reduces risk of infection and makes maintenance easier
• Reusable with releasable arrangement, promoting sustainability and cost-efficiency

Patent Abstract

The arrangement has a resonance sensor (1) provided with an oscillating circuit, where the oscillating circuit is made of a conductive thread like carrier. The carrier is formed as a continuous structure, a coil structure (11) and a capacitor structure (12). The oscillating circuit is directly stitched on or into an incontinence material that is releasably arranged on or in a support material (2). The sensor is wirelessly supplied with energy, and capacitively detects moisture. The sensor is stitched as a flat structure on the incontinence material. The support material is made of non-woven fabric.
