Imec and TU Delft develop revolutionary wireless EEG headset using 3D printing
As wireless technologies – such as wireless internet and Bluetooth – continue to find their way into a number of “smart” consumer electronic devices, we’re also starting to see how these powerful technologies can also be used in a number of non-traditional lifestyle applications, too – such as devices used in the medical industry.
Imec and the Holst Centre – along with the Industrial Design Engineering (IDE) faculty of Delft University of Technology (TU Delft) – have announced a unique application for existing wireless technologies with their new wireless electroencephalogram (EEG) headset that can be worn comfortably and achieves a high-quality EEG signal. The headset enables effective brain-computer interfacing and can monitor emotions and mood in daily life situations using a smartphone application.
The new headsets, which feature dry electrodes and are easy to apply and support long-term daily life monitoring, can be used for a number of different applications outside of the medical tracking, too – including next-generation video games that monitor relaxation, engagement and concentration during game activity. For medical-related applications, the device can be used for attention training, sleep training and treatment of Attention Deficit Hyperactivity Disorder (ADHD), among others.
To create the futuristic medical wearable, the design team turned to 3D printing in order to develop the headset as a single piece. According to imec, the base of the headset is 3D printed in a single piece, followed by the installation of electronic components, followed by a rubber inlay created on a 3D printer. In order to allow for optimal EEG signal acquisition related to emotion and mood variations, the sensors that acquire the EEG signal are situated at the front of the headset.
