Remote incontinence detection and monitoring system with method and manufacturing method thereof

A process for providing a RF tag for monitoring the excretion, comprising:

• providing at least three layers including two conductive layers and an insulation layer in between, thereby forming at least one capacitor and at least one inductor with the two conductive layers;
• wherein the RF tag is configured to respond to a signal at a frequency and the contact of any exposed part of the two conductive layers with the excreted fluid modifies the response by the RF tag to the signal at the frequency.

An excretion monitoring system, comprising a plurality of RF tags each of which is configured to respond to a signal at a different frequency, wherein the excretion modifies the response by the RF tag contaminated by the excreted fluid to the signal at its respective frequency.

A method for monitoring excretion with an excretion monitoring system, wherein the excretion monitoring system comprises a plurality of RF tags each of which is configured to respond to a signal at a different frequency, and wherein the excretion modifies the response by the RF tag contaminated by the excreted fluid to the signal at its respective frequency, the method comprising:

• transmitting, to each of the plurality of the RF tags, a signal at its respective frequency;
• determining the response by the each of the plurality of the RF tags to the signal;
• determining, from the responses of the plurality of the RF tags, whether and/or which RF tag(s) is/are contaminated by the excreted fluid.

A method for detecting the excretion by using an excretion monitoring system with multiple RF tags each of which is configured to respond to a signal at a different frequency, wherein the contact of a RF tag with the excreted fluid modifies the response by that RF tag to the signal at the corresponding frequency, comprising:

• for each of the multiple RF tags, transmitting a signal and receiving the response from that RF tag;
• detecting the excretion based on the response.

A method for detecting the excretion by using an excretion monitoring system with multiple RF tags in a matrix that comprises two sets of intersecting groups, wherein each group of RF tags in one of the two sets is configured to respond to a signal at a different frequency and the contact of a RF tag with the excreted fluid modifies the response by that RF tag to the signal at the corresponding frequency, comprising:

• for each group of RF tags in the one of the two sets, transmitting a signal at the corresponding frequency and receiving the response from that group of RF tags;
• determining a group of RF tags in the one of the two sets as being in contact with the excreted fluid when all RF tags in that group fail to respond to the signal at the corresponding frequency as configured.
