A noninvasive smart wearable for diaper moister quantification and notification

Abstract

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.

Wearable and Flexible Humidity Sensor Integrated to Disposable Diapers for Wetness Monitoring and Urinary Incontinence

“…Bluetooth technology was used to automatically detect incontinence and its volume. In another study, a smart gadget attached to the outside of the diaper for urine detection determined the temperature increase and sent a notification to the caregiver's smartphone [16]. However, the external, inflexible, and rigid devices used in these studies may cause urinary incontinence patients to be uncomfortable with the presence of these devices.…”

A Low Power IoT-Connected Smart Canister System Creating Automatic Shopping List

“…A prototype of the proposed system with three canister devices, one hub, and the smartphone app is developed and tested successfully.Smart homes and IoT are automating the ability to control and monitor items around the housefrom window shades to pet feeders-with a smartphone or using voice command. Some activities, like setting up a lamp to turn on and off [4], monitoring a baby's diaper wetness [5,6], controlling and monitoring chicken eggs in incubator [7], are some examples. Several works are found in the literature on generating shopping lists using IoT and smart home technology.…”
