A body sensor should be as unobtrusive as possible to have the smallest impact on the ordinary behavior of the patients under examination. The keys of invisibility are the low profile construction, technological innovation and the perfect adhesion to the skin. Dab is aimed to minimize medical instrument size by reducing electrode distances. The redesigned way of applying the sensor onto the body makes it effortless and intuitive. Thanks to these changes Dab can achieve better user experience, while significantly reducing disposable items, manufacturing and maintenance costs.
