“…The existing RFID based diaper wetness sensing systems are built on the customized RFID tags [53,54,64,66], which need to design the specific tag's antennas and circuits. These customized and complex RFID tags rely on expensive and customized reader to power them up.…”

“…The complex circuit components require much more power to activate the tag, which will cause low reading range (<30cm). The passive HF RFID tags [64,66] are designed, which are expensive and require the displacement of the diaper material. The UHF RFID tag [53] is designed for diaper wetness sensing based on the hydrogel sensing.…”

“…To achieve the predictive health care and at-point diagnostics for diaper wearers, the embedded sensors and customized RFID tags [46,53,53,54,64,66] are designed to alert the caregivers, whenever the diaper is wet and needs to be replaced. The sensor based diaper wetness detection system is bulky [7,9,15,39], which needs to be hooked to the commodity diaper uncomfortably.…”

In this paper, we present RFDiaper, a commodity passive RFID based healthy diapering system, which can sense the diaper wetness (i.e., wet/dry) and identify pH value of urine absorbed by the diaper. To do so, we leverage the coupling effect between the urine absorbed by the diaper and RFID tag, thereby the phase and amplitude variation can indicate urine pH and diaper wetness. However, rich scattering and dynamic environment exhibit a great challenge for accurate diaper wetness sensing and urine pH identification. Therefore, we propose a twin-tag based dynamic environment mitigation approach for robust and healthy diapering. Specifically, by extracting the differential amplitude and phase from the co-located sensing tag and reference tag (i.e., twin-tag) attached on the diaper, the multipath effect and the other dynamic factors (e.g., diaper wearer's body, tag's orientation and temperature, etc.) can be mitigated. Then, we detect the diaper wetness and estimate the urine pH based on differential amplitude and phase. We have implemented RFDiaper's design and evaluated its effectiveness with the experiments using commercial off-the-shelf (COTS) RFID tags attached on the diaper worn by the doll and the human subjects. RFDiaper can achieve the median accuracy of around 96% for diaper wetness sensing and urine pH estimation error of around 0.23 in dynamic environment.

“…As the Internet of Things related systems and Health Information technologies (HIT) develop, intelligent devices that reduce nurses' increased workload and support EC are introduced. For example, there are wireless systems that monitor diaper wetness, [12][13][14][15][16] a carebidet robot that detects and sucks urine and feces and cleans and dries the skin, 17 and a robot that transfers patients between a wheelchair/bed and a toilet. 18,19 However, these devices remain limitedly adopted in nursing since they have not been as helpful as expected in reducing the EC burden on nurses and their effectiveness has not been thoroughly verified.…”

Background Inpatients commonly experience problems with elimination due to incontinence, urinary retentions, and complications with indwelling catheters. Although elimination care (EC) is an important nursing area, few studies explore the burden of EC on nurses. Aim To identify the burden on EC by analyzing nurses’ opinions using sequential explanatory mixed method. Methods This research was conducted using a sequential explanatory mixed-methods design. A total of 59 nurses at a tertiary hospital in South Korea participated in the study from January 1 to March 31, 2022. For quantitative analysis, information about number of delays of work due to EC, required time for serving bedpan or diaper changes, percentage of EC per shift, and percentage of patients who need EC was collected through a survey. For qualitative analysis, focus group interviews were conducted to identify factors that put a burden on EC. Important themes were derived by analyzing nurses’ opinions on EC. Results For nurses in intensive care units, general wards, and integrated nursing care wards, the number of work delays due to EC was 3.6 ± 1.5, 2.3 ± 1.2, and 4.8 ± 2.4 ( p <0.01), respectively. The mean percentage of EC work out of total nursing tasks per shift was 36.2 ± 19.0, 29.3 ± 14.4, and 43.8 ± 14.1 ( p =0.02), respectively. The mean percentage of patients requiring EC out of patients a nurse cares was 85.4 ± 16.6, 41.3 ± 26.1, and 58.8 ± 21.9 ( p <0.01), respectively. Following qualitative analysis, four themes related to nurses’ EC burden were derived: physical burden, frequent care needs, delay of other jobs due to EC, and complications. Among them, frequent care needs were found to be the primary factor requiring consideration to reduce nurses’ burden. Conclusion This research found that EC is one of the most burdensome tasks that nurses want to avoid. To alleviate their burden, effective EC protocol or smart medical devices assisting with EC should be developed.

“…However, the GSM module consumes approximately 2 A current during transmit burst and it is difficult to design a small size coin cell battery operated power supply for this module. In [19][20][21][22], Radio-frequency identification (RFID) circuit based moisture detection system is developed where the disposable sensors need to go inside the diaper, thus new diaper production process is required. This will increase the cost of each diaper and the distance covered by RFID-based systems is only 1 to 1.5 meter.…”

A noninvasive smart wearable for diaper moister quantification and notification

A baby feels uncomfortable in a wet diaper and it can cause health issues such as diaper rash. Diaper rash can be avoided by changing the diaper as soon as the baby urinates or passes stool. In this project, a smart wearable gadget is developed which sends an automatic notification to a caregiver’s smartphone whenever the baby urinates. The proposed wearable detects urination event noninvasively by sensing the temperature rise on the outer surface of the diaper and quantifies the event using a decision tree and a midpoint based k-nearest neighbor (KNN) hybrid classification algorithm. The gadget is a small size, low power, low cost and reusable electronic device that is attached externally to the outer surface of the diaper. The gadget can be used with any disposable diaper, thus no change in the diaper production process or price increase is required. The smartphone app shows the diaper change urgency score and logs all the urination events. This record can facilitate treating diseases where accurate records of urination are required. A prototype of the hardware gadget and a smartphone app is developed and tested.
