Almost 2 years have passed since we first posted about the development of a new wireless EEG headset prototype by Imec and voilà, roughly 20 months later the Belgian company has announced, in collaboration with Panasonic and Holst Centre, an 8-channel, easy-to-setup wireless headset aiming to diagnose epilepsy and help with ADHD.
This second-generation headset has changed a lot compared to the first version we saw years ago. The shape has not changed much but the cover has been replaced with a transparent plastic (check out the early white prototype) and more importantly the new prototype has greater accuracy and flexibility and more ease of use than the earlier model. The new headset has active electrodes instead of passives, more flexibility, can accept more electrodes as needed, and has less interference.
The heart of the system is still the same, a low-power 8-channel EEG monitoring chipset from Imec. Each EEG channel consists of two active electrodes and a low-power analog signal processor. The EEG channels are designed to extract high-quality EEG signals under a large amount of common-mode interference. The active electrode chips enable recordings from dry electrodes, and do not require the use of shielded wires.
The device is now going into pre-clinical validation but industry professionals have been able to get access to the technology since 2010. What they need to do is joining imec’s Human++ program as research partner or by licensing agreements for further product development. Within the Human++ program, imec and Holst Centre develop solutions for an efficient and better healthcare.
To see the device in action and to understand how the Imec headset is different from traditional EEG research caps, watch the video below.
Separately, Imec announced it is working with Tokyo Electron Ltd. (TEL) to develop imagers and sensors to assist in growing stem cells outside the human body.
“There’s a lot of interest in growing cells for tissues and ultimately organ transplants,” said Paru Deshpande, program director for life sciences at Imec.
