In 1924, almost 100 years ago, Hans Berger discovered that brain electrical activity can be non-invasively recorded from the human head by placing sensors on the scalp. Today, multi-channel ElectroEncephaloGraphy (EEG) is well established in neuroscience research and clinical applications, typically requiring an elastic cap or net to hold the sensors in place. In addition, a conductive paste or gel is necessary as a bridge between electrode and skin.

UN Goal
Twente Medical Solutions International or TMSI for short is one the world’s market leaders in this field which continuously pushes the boundaries of what is possible in EEG. Together with the brilliant engineers and scientists of TMSI ManGo was integrally working on the cEEGrid project which aim was to enable unobtrusive EEG measurements. In other words, create a system which is less time consuming to use, avoids discomforts whilst wearing, limits the use of gel and is less obvious than EEG-caps and thus not distracting in real-life situations.
The result of all our efforts are cEEGrids; flex-printed, multi-channel sensor arrays that are placed around the ear using an adhesive. cEEGrids are lightweight, comfortable to wear and discrete; some users have even reported to forget they are wearing them completely.
ManGo Product Design was responsible for determining ergonomic factors of how the system would be worn and placed on the patient’s body, integration of electronics in the housing, creating prototypes and production runs of several components of the system. Last but not least the styling of the housing was the first step for a complete overhaul of TMSI’s product range and branding.
