Here is a smart wearable device designed for people dealing with urinary incontinence. This non-invasive sensor attaches to your body and uses ultrasound to monitor the bladder all day long. The data is analyzed to let you know when you should go to the bathroom.
The data can be uploaded to the cloud over WiFi for remote monitoring of patients by physicians. The DFree transmitter weighs only 2.5 ounces. Its battery lasts up to 24 hours.
