Dreem is lucky enough to have a number of brilliant employees. We’re hardworking and innovative. Best of all, we’re always learning. So we thought we’d put all this collective knowledge to the test. In our new series “Tough Questions,” we ask Dreem team members some burning questions. From how exactly we build our product to what makes the brain work the way it does. Today, we asked Kaveh Mohamadabadi, Head of Hardware Electronic Design at Dreem. How do you pack so much technology into one wearable device?
“Thanks to a bunch of recent research and development on nanoelectronic technology and MEMS (microelectromechanical systems) sensors, today’s wearable devices can bring advanced technology even closer to individuals.
Year after year, embedded electronics are becoming more efficient, smaller, and less power-hungry. It means that they work on a more independent scale, like on a person’s fitness tracker or sleep wearable. Today’s wearables are always “on.” Health monitoring applications, sports trackers, and navigation systems are constantly measuring and gathering data behind the scenes. So whenever the wearer wants to access, the device is ready.
Focus on great efficiency and a positive user experience with Kaveh
When it comes to the Dreem headband, we really focus on greater efficiency and a positive user experience. In engineering the device, we gathered the most advanced technologies — from computation power, high-resolution measurement of the brain, heart, and body, wireless connectivity, power efficiency — and squished them into one tiny package.
It sounds tough to pack that all in, but I’ll give you an example. The electronic design of the Dreem headband is divided into two simple parts. First, the ultra-low power computation module. It provides computing power at a small scale that still packs as big of a punch as any smartphone on the market And second, the ultra-low noise acquisition module. It measures brain activity during sleep. All this technology enables us to make the acquisition, processing, and sound stimulation of the brain activity in real time and in a safe and non-invasive way.
Keeping the device efficient but still powerful comes from leveraging the latest technology on the market and a super smart team that knows how to work with it. We may have ironically lost some sleep along the way. But I can’t wait for the Dreem community to try out Dreem!
Thank Kaveh for this interview!
