Abstract

Absorbent articles with biodegradable and/or biocompostable elements are disclosed, wherein the absorbent articles include sensors. The sensors detect and determine variables associated with collected fluids, solids, and gases, including a presence of fluids, solids, and gases, a volume of fluids, solids, and gases, and/or a distribution of fluids, solids, and gases. In one embodiment, the sensors and/or connected computing systems are calibrated to capacities and other properties of elements within the articles, including superabsorbent polymers, and are operable to trigger an alert based on detected or determined conditions.

9. The system of claim 1 , wherein the sensor is further configured to detect a quality of a seal of the absorbent hygienic article to a body of a user of the absorbent hygienic article.

10. The system of claim 1 , wherein the sensor is further configured to detect at least one variable associated with a menstrual cycle, wherein the at least one variable includes a color, a saturation, and/or a material composition of the liquid.

11. A sensor system for absorbent hygienic articles comprising:

a sensor; and

a computing device,

wherein the sensor and the computing device are in network communication;

wherein the sensor is configured to detect a presence of a liquid, a solid, or a gas in an absorbent hygienic article and/or properties of the liquid, the solid, or the gas in the absorbent hygienic article and communicate the presence of the liquid, the solid, or the gas in the absorbent hygienic article and/or the properties of the liquid, the solid, or the gas in the absorbent hygienic article to the computing device;

wherein the computing device is configured to generate an alert based on the presence of the liquid, the solid, or the gas in the absorbent hygienic article and/or the properties of the liquid, the solid, or the gas of the absorbent hygienic article; and

wherein the computing device is configured to synchronize data obtained from the sensor with another application on the computing device or another application on a separate computing device.

12. The system of claim 11 , wherein the computing device includes a graphical user interface (GUI), wherein the GUI is configured to display a notification that fecal matter has been detected by the sensor and/or a notification that urine has been detected by the sensor.

13. The system of claim 11 , wherein the computing device is configured to analyze data from the sensor to estimate an end date for a menstrual cycle based on historical data.
