Summary
This study developed comfortable, washable textile underwear with integrated sensors to detect bedwetting. This innovation aims to improve treatment acceptance and achieve nighttime dryness for enuretic children.
Area of Science:
- Textile Engineering
- Biomedical Engineering
- Pediatric Urology
Background:
- Bedwetting (nocturnal enuresis) affects approximately 15% of children over five.
- Existing bedwetting alarms are effective but often uncomfortable, leading to poor compliance.
- There is a need for more comfortable and acceptable solutions for managing childhood bedwetting.
Purpose of the Study:
- To develop a comfortable, unobtrusive, and washable urine leakage sensor integrated into children's underwear.
- To enhance the acceptability and effectiveness of bedwetting alarms for enuretic children.
- To improve the quality of life for children experiencing nighttime dryness issues.
Main Methods:
- Fabrication of urine leakage sensors using conductive textile metallic yarns (silver and stainless steel).
- Evaluation of sensor performance, including conductivity, urine detection capability, and speed.
- Testing sensor durability through multiple urine soakings and machine wash cycles at 60°C.
- Adaptation of the detection circuit to mitigate silver corrosion.
- Seamless integration of the sensor into child-sized textile underwear.
Main Results:
- Silver-plated-nylon yarn demonstrated superior electrical conductivity and faster urine detection compared to stainless steel.
- The textile sensor successfully withstood multiple urine exposures and machine washings at high temperatures.
- Circuit modifications addressed silver corrosion issues related to electrical current.
- The final design features a miniaturized alarm plug-in for the integrated textile underwear.
Conclusions:
- Seamlessly integrated textile underwear with a conductive yarn sensor offers a more comfortable and acceptable alternative to traditional bedwetting alarms.
- This innovative approach has the potential to improve treatment adherence and achieve nighttime dryness in enuretic children.
- The developed system enhances comfort and quality of life for children with nocturnal enuresis.

01:23Urinary Bladder
2.7K
The urinary bladder is a hollow, muscular sac that temporarily stores urine before it is expelled from the body. It can hold approximately 600 mL of urine prior to micturition. The bladder is retroperitoneal and located behind the pubic symphysis in the pelvic floor.
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...

01:26The Micturition Reflex
2.1K
Urination, or micturition involves the coordination of the bladder's detrusor muscle and two sphincters to ensure controlled bladder emptying.
The process begins with bladder filling, where the bladder wall stretches as urine accumulates. This stretching activates the urine storage reflex, mediated by the sacral spinal segments and the pontine storage center. Efferent sympathetic impulses stimulate the detrusor muscle to relax and the internal urethral sphincter to contract, facilitating...

01:57Adaptations that Reduce Water Loss
27.7K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

01:19Urodynamic Studies: Uroflowmetry
2.2K
Uroflowmetry is a non-invasive urodynamic test designed to measure various aspects of urination, including volume, flow rate, and the time to void. This test is crucial for diagnosing and assessing conditions such as bladder outlet obstruction, bladder dysfunction, incomplete bladder emptying, incontinence, and urinary tract blockages caused by benign prostatic hyperplasia (BPH) and urethral strictures.Pre-Test Instructions:Before a uroflowmetry test, patients are typically advised to drink...

01:32Filtration and Urine Formation
52.8K
The function of the kidneys is to filter, reabsorb, secrete, and excrete. Every day the kidneys filter nearly 180 liters of blood, initially removing water and solutes but ultimately returning nearly all filtrates into circulation with the help of osmoregulatory hormones. This process removes wastes and toxins but is also crucial to maintain water and electrolyte levels. Most of these functions are performed by the tiny but numerous nephrons contained within the kidneys.

01:19Anatomy of the Genitourinary System II: Bladder and Urethra
895
The lower urinary system consists of the urinary bladder and urethra, which are essential in storing and expelling urine from the body. Together with the internal and external sphincters, these structures work together to regulate urination effectively.Anatomy of the BladderThe urinary bladder is a muscular, stretchable organ behind the pubic bone and in front of the rectum. In females, the bladder is positioned anterior to the vagina and inferior to the uterus, while in males, it is located...
