Frequently Asked Question

Most of the time a question is already answered. Check out the Frequently Asked Questions page to see if you have that question.

For who?

The SENS-U monitors the filling of the bladder and gives a notification when the bladder is nearly full via a vibration in the SENS-U and/or a message on a smartphone. The user is notified that the bladder is full and action should be taken. The SENS-U Bladder Sensor helps to prevent unwanted urinary loss. 

The SENS-U KIDS is intended for schoolchildren who are under the treatment of a medical professional. It teaches children who are late with toilet training to go to the toilet when their bladder is full.

How does it work

The SENS-U is a non-invasive wearable sensor that uses ultrasound to detect how full the bladder is. The SENS-U bladder sensor is placed on the lower abdomen using a double-sided adhesive plaster. Ultrasound gel and a plaster are applied between the sensor and the skin to guarantee ultrasound conductivity and ensure it remains in the correct position. The measurement details are processed in the SENS-U, and the data is sent to a smartphone via Bluetooth.

The SENS-U is a non-invasive wearable sensor using ultrasound technology to measure bladder filling. The SENS-U Bladder Sensor is placed on the lower abdomen with an adhesive patch. Between the sensor and the skin, ultrasound gel and an adhesive patch are used to ensure ultrasound conduction and fixation. The sensor data is pre-processed in the scanner, and data is sent to a smartphone using Bluetooth.

How do I get SENS-U?

Urologists and pediatricians are using the SENS-U bladder sensor in numerous Dutch hospitals. We’ll be happy to inform you about the entire process from GP to hospital, and are of course always here to answer any other questions you may have. Send us a message and we’ll aim to reply within 24 hours.

The SENS-U® bladder sensor is medically CE-certified and available for care providers in Europe. They can purchase the SENS-U directly from Novioscan or a local dealer, and use with their patients right away. Contact us for more information.

During Use

The SENS-U starter kit contains everything you need to start using the sensor right away: adhesive plasters, ultrasound gel, alcohol swabs, and the SENS-U itself. Download the SENS-U app on your smartphone from the Google Play Store or App Store. Follow the instructions to set your preferences.

The SENS-U and smartphone are connected to each other wirelessly via Bluetooth Low Energy, so the device also works without WiFi

The SENS-U can connect to one smartphone at a time. It is possible, however, to also forward the full bladder notification to a second smartphone. You can find this option in the app menu under the bell icon.


The SENS-U bladder sensor is certified as a class IIA medical device, and has had CE mark since March 2018.

Novioscan has been ISO 13485 certified since March 2018.

The SENS-U bladder sensor is a device for children aged 6 to 16 who have difficulty sensing when their bladder is full. The wearable device uses ultrasound technology and has been developed in collaboration with University Medical Center Utrecht.

SENS-U sends timely reminders to help the wearer better recognize the sensation in their bladder. So that, over time, wet accidents can become a thing of the past.

SENS-U Sensor
SENS-U 2.0


The SENS-U Bladder Sensor is our first major breakthrough in wearable ultrasound aids. The SENS-U helps children aged 6 to 16 who have difficulty recognizing when their bladder is full.


Dutch innovation

Developed and produced in the Netherlands, the SENS-U® is being used successfully by children. Wearers and medical specialists alike are very enthusiastic about the results. We’re constantly improving our products by incorporating direct feedback from users and medical professionals, because it’s our ambition to improve the lives of people with bladder incontinence.

Effective and discreet

The SENS-U 2.0 is a compact, wireless device that is stuck to the lower abdomen using a specially developed plaster. When it’s time to go to the toilet, the sensor gently vibrates on the lower abdomen or sends a notification to the smartphone app – so only the user receives a discreet warning, without anyone else realizing.


Benefits at a glance

Wireless wearable ultrasound sensor
Wireless, wearable ultrasound sensor

You can wear the SENS-U day and night. You simply use a double-sided plaster to stick the sensor on your lower abdomen. The SENS-U connects to your smartphone via Bluetooth.

Position control
Help to check the correct position

The SENS-U app helps to identify the right position on the lower abdomen, so the sensor can correctly detect how full your bladder is. A green screen indicates that the sensor is located right next to the bladder.

Personalized notification
Personal notification settings

You can set the level for how full the bladder can reach before the SENS-U sends you a notification. You can also decide how strong you want the vibrations to be. So the sensor is always set to your personal preferences.

Discreet notification
Discreet and only for you

The SENS-U vibrates on your lower abdomen at a strength you set for yourself, or sends a message to the app on your smartphone, to warn you of a full bladder. So no one notices anything except you

Independent notification
Also works without the app

Even when the SENS-U is not connected to your smartphone, you still receive reminders for when to go to the toilet. So you don’t need to worry if you don’t have your phone to hand.

Voiding Diary
Urination diary provides insight

The SENS-U includes an app for keeping track of when you last went to the toilet, and tells you whether and how you received a notification. So the urination diary can also keep a record of when you made it on time.

See how it works

What do users say?

He only had to catheterize 4 x per day with the sensor, as opposed to 5 x per day without a sensor. In addition, no wet pants during the 3 weeks using the SENS-U!

The ‘bladder sensor’ finds its way to hospitals

The ‘bladder sensor’ finds its way to hospitals

A portable bladder sensor for children who suffer from unwanted leakage of urine finds its way to hospitals and care institutions in cities such as Nijmegen, Utrecht and Zwolle. Several hundred of this Nijmegen invention will be sold this year, says Novioscan director Rob Tweehuysen. This Nijmegen start-up is the developer of the bladder sensor.

Check out the full Dutch article here.

Since last year, dozens of devices have been sold. Meanwhile, the Radboudumc and the Isala hospital in Zwolle are connected. But the big market is that of elderly people who are incontinent, says Tweehuysen. Novioscan is now developing a sensor for this target group. He thinks it will be on the market by mid 2021.

BOSK about the SENS-U KIDS

BOSK about the SENS-U KIDS

In the December 2018 issue of the BOSK you could read about the SENS-U KIDS of Novioscan. This portable mini-echo machine gives a signal to children from 6 – 12 years old when the bladder is full. This means that children no longer need to be incontinent with urine. A noticeable signal is given when it’s time to urinate. A signal can also be received via an app. Children who may benefit from the use of the SENS-U, such as incontinence training, can use the device with a lending service via the urologist. In addition to the Wilhelmina children’s hospital in Utrecht, 10 hospitals in the Netherlands now use the SENS-U. Want to know what BOSK has to say about the SENS-U KIDS in Dutch click here.
