The SENS-U bladder sensor accurately notified children when their bladder was full during daily activities. Children responded well to these personalized alerts, showing its potential for managing urinary incontinence.
Area of Science:
- Pediatric Urology
- Biomedical Engineering
- Wearable Technology
Background:
- Urinary incontinence is a common issue in school-aged children.
- The SENS-U Bladder Sensor is a new wearable ultrasonic device for monitoring bladder fullness.
- It provides personalized alerts to prompt timely toilet use.
Purpose of the Study:
- To evaluate the performance of the SENS-U Bladder Sensor.
- To assess its effectiveness as a full-bladder notification system for children during daily life.
- To determine its accuracy in monitoring natural bladder filling.
Main Methods:
- A pilot study included 15 children (aged 6-16) undergoing inpatient bladder training.
- The SENS-U sensor was worn during daily activities to estimate bladder filling.
- Children alerted a urotherapist/researcher upon receiving a full-bladder notification.
Main Results:
- The SENS-U achieved a median notification rate of 92.9% based on personalized thresholds.
- Children responded to 100% of notifications, indicating high engagement.
- Occasional voids occurred before the notification, such as during defecation.
Conclusions:
- The SENS-U accurately monitors bladder filling during daily activities.
- It effectively provides personalized, timely notifications for children.
- Further research will compare its efficacy against current clinical practices.

Urinary Bladder
In males, the bladder is situated in front of the rectum, while in females, it is positioned anterior to the vagina and uterus. The bladder floor contains an inverted triangular area called the trigone, defined by the two ureteric...
