“…In the research community, there are also works related to urine detection devices or sensors. Wu and Siegel 8 from Carnegie Mellon University proposes a low-cost odor-based sensor to monitor incontinence, while Ejaz et al 9 designed a system for measurement of urine as well as its components using reagent paper. Tamura et al 10 from Tokyo Medical and Dental University proposed a system based on the principles of temperature and impedance changes to detect urine.…”

Incontinence is highly prevalent in the elderly population, especially in nursing home residents with dementia. It is a distressing and costly health problem that affects not only the patients but also the caregivers. Effective continence management is required to provide quality care, and to eliminate high labor costs and annoyances to the caregivers resulting from episodes of incontinence. This paper presents the design, development, and preliminary deployment of a smart wireless continence management system for dementia-impaired elderly or patients in institutional care settings such as nursing homes and hospitals. Specifically, the mote wireless platform was used to support the deployment of potentially large quantities of wetness sensors with wider coverage and with dramatically less complexity and cost. It consists of an intelligent signal relay mechanism so that the residents are free to move about in the nursing home or hospital and allows personalized continence management service. Preliminary results from a trial in a local nursing home are promising and can significantly improve the quality of care for patients.

“…1,2 The most common sensor technology incorporated into disposable BWAP is a wet alarm system that detects involuntary urine loss by measuring increases in humidity and temperature or by the presence of ammonia gas in the urine, and alarms the nurse through a signal like a text, graphic, or sound. 5 Multiple studies examined the effectiveness of urine detection sensor technology 2,[6][7][8][9] and some tested sensors with extra functionalities such as the detection of abnormalities in urine 10 or fecal odor. 11 Because nursing home residents, nurses, and facility leadership are end users of sensor technology, we assert they must be involved throughout the development process of such technology.…”

PURPOSE: The purpose of this study was to define the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. DESIGN: Qualitative study using a framework method. SUBJECT AND SETTING: The sample included residents with incontinence, nurses, and decision-makers in a selection of Flemish nursing homes (Belgium). METHODS: Semistructured interviews were performed between June and August 2020. The interviews with nurses included open-ended questions focusing on the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. The interviews with decision-makers were supplemented with questions about purchase cost and other economic criteria (such as reimbursement). Interviews with residents included questions about wearing comfort. Interviews were tape-recorded and transcribed verbatim. Data were analyzed using a framework method. RESULTS: The user profile was defined as (1) residents with cognitive impairment and (2) residents who are bedridden or are severely limited in mobility. The following (technical) criteria emerged from the analyses: a small, thin, and oval/circular sensor, an adaptable or in front attachment of the sensor on the absorbent product, a real-time indication of the absorbent product's saturation, leakage detection, liquid stool detection, the automatic recording of incontinence-related data, a durable sensor easy to disinfect, and receiving notifications on a wearable device. Conditions included a stable connection between the wearable device and the sensor, accurate measurements, user-friendly system, comprehensible training, affordability, and data protection. Potential benefits included workload reduction, increased comfort for residents and staff, more person-centered care, increased quality of care, less skin damage and economic (eg, less costs due to less excessive absorbent product changes), and/or environmental (e.g. less waste) gains. CONCLUSION: Study findings identified the user profile, (technical) criteria, conditions, and potential benefits of the integration of sensor technology in disposable body-worn incontinence materials. Respondents reported problems with changing routines and skepticism about the sensor's accuracy. Based on findings from this study, we recommend involving representatives of all relevant stakeholders in the design of sensor technology to ensure users' needs and increase the use of sensor technology. Comprehensive education is recommended to inform nurses, residents, and their family members on the importance and benefits of the technology and to aid overcoming barriers to use (skepticism, resistance to new technologies, and changing care routines). Study findings also indicate that the sensor technology cannot replace the existing voiding programs; rather it should be an addition to routine continence care.

A wide range of wearable devices are now used to help people with various health conditions. While approximately 10% of the Canadian population is affected by some form of urinary incontinence, there is a significant need for devices addressing this condition. This paper presents an ongoing research project for the design and development of an underwear fitted with urinary detection capacities. The paper focuses on the testing and comparison of three different solutions identified from scientific literature for detecting urinary leakage, namely by measuring conductivity, temperature, and humidity. These three detection modules have been integrated into a single prototype to ensure that they are tested under the same conditions. Our results point out that conductivity and humidity measurements appear to be viable for urine leakage detection in an absorbent pad, whereas temperature measurement has proven to be unsuccessful due to the rapid drop of the solution temperature and the time required for the liquid to reach the sensor. The temperature method is hence excluded from the next development stages. Finally, further tests on participants are still required to evaluate how body fluids other than urine might impact conductivity and humidity measurements.
