Belly Bean Fetal Doppler

The fetal doppler is a non-invasive diagnostic device used to detect and measure the fetal heart rate which allows to evaluate fetal wellbeing. Reports shows that over 78% women are worried about their baby’s health during pregnancy. The possibility to check if everything is allright with the baby whenever possible will give a peace of mind and relief from worrying.

Belly Bean is advanced project of new generation fetal dopppler connected with app and adjusted packaging. Belly Bean is ergonomic and intuitive. New technology provides wireless integration with smartfon which aims to increase comfort of use and adds the new features and services like heart rate analysis and personalized recomendations or data transmision to medical care units, which allows to support and care for baby and the mother from the distance.



The main factor was to improve functionality and safety. Incomprehensible interface, ignorance associated with the use and inability to save results may raises many doubts and inconvenient situations for pregnant women. Women are interested in domestic use of fetal dopplers, however, these devices do not provide the necessary knowledge and functions which allows to use them in an effective way.


Shape of Belly Bean is result of ergonomic tests. Many prototypes were made to achieve the most comfortable form, adjusted to hand and belly.

Prototypes was made of a modeling foam on the lathe and the milling machine. 3d printer was used to create the final prototype. Project was made in Rhinoceros.






I think I learnt how to effectively implement technology and lifestyle trends into the products and how important is to constantly look forward.
This project has an huge impact on my perception of design process at present.

In general people respond very well to my project and I heard many positive opinions.

Belly Bean is my graduate diploma at the level of a bachelor’s degree.
