Abstract
One example embodiment is a device for detecting fullness of a bladder of a subject. The device includes a distension sensor, an electromyography (EMG) sensor and a microcontroller. The distension sensor is located on a waistband of a pant and detects changes to a curvature of skin adjacent the bladder. The EMG sensor is located in the pant and includes two EMG electrodes that detect potential difference caused by contractions of the bladder. The microcontroller processes signals received from the distension sensor and the EMG sensor and generates, based on the signals, an output value that indicates the fullness of the bladder.

A device for detecting fullness of a bladder of a subject, comprising:
- a distension sensor that is located on a waistband of a pant and that detects changes to a curvature of skin adjacent the bladder of the subject;
- an electromyography (EMG) sensor that is located in the pant and that includes two EMG electrodes that detect potential difference caused by contractions of the bladder of the subject;
- a heart sensor that is located in the pant and that detects a heart rate variability (HRV) of a heart of the subject;
- and
- a microcontroller that processes signals received from the distension sensor, the EMG sensor and the heart sensor, and generates, based on the signals, an output value that indicates the fullness of the bladder,
- wherein the output value is generated based on the Equation
- Output value=−22+31*Distension+1.77*Heart Rate Variability−3.07*Amplitude of EMG.
A method of measuring a fullness of a bladder of a person wearing an undergarment, the method comprising:
- sensing, with an electromyography (EMG) sensor provided in the undergarment worn by the person, changes in electric potential of the bladder of the person;
- sensing, with a distension sensor provided in the undergarment worn by the person, changes in curvature of the bladder of the person;
