TENA SmartCare Bladder Sensor is a wearable ultrasound device that continuously monitors the bladder’s fullness to help prevent incontinence. With gentle vibrations and real-time updates sent to a smartphone or Apple Watch, it discreetly notifies when it's time to go to the toilet. The sensor supports in bladder training, with reminders when the bladder filling level gets high, allowing to understand the sense of urgency better to avoid leaks. It is suitable for both children and adults, and it has shown to reduce involuntary urinary loss by 67%* after only one week’s use.

This small, discreet, lightweight sensor uses non-invasive ultrasound technology to monitor the bladder in real-time. It connects to your smartphone** or Apple Watch via Bluetooth®. Users can set personalised thresholds on when to get notified before the bladder is completely full, i.e. reaching 50% or 70% bladder fullness, allowing for greater control and better planning for when to visit the bathroom.

The TENA SmartCare Bladder Sensor app tracks the bladder filling and automatically logs voidings, as well as allowing for manual entry of any additional voiding or leakage. This creates a detailed and insightful bladder diary that can be shared with healthcare professionals. The smartphone app also provides daily, weekly, and monthly overviews, helping users identify trends and better understand their voiding habits.

The sensor is easy to apply on your lower abdomen, with sensor gel for the ultrasound and adhesive patches to keep your sensor securely in place. Designed for daily use, the sensor can be worn at home, during activity, on-the-go, and both during the day and night. The battery lasts for several days and fully recharges in 2 hours, ensuring it can be readily available for use.

After just one week of use, 77% of users report improved control*, with 80% recommending the product*. The TENA SmartCare™ Bladder Sensor helps you get to know your bladder better and stay in control by knowing when to go to the toilet.
