Cogna

A Neurotech Startup

During my sophomore year at Tufts, 3 of my friends and I got together to find a solution for our shared inability to get good consistent sleep. We decided to apply what we had learned in class about neurostimulation and build a wearable headset that uses transcranial electrical stimulation (tES) to help users fall asleep faster. As the head of research in our team, I gathered findings from scientific literature and our user research surveys to define our headset's key functional design features.

We eventually got enough traction to turn our project into a fully fledged startup that we called Cogna, and we were off to the races. The 2 following years were filled with caffeine-fueled brainstorming sessions, electrical engineering crash courses, destroyed prototypes, and a few successful pitches that secured us enough funding to finally finish building our headset. 

We were getting ready to launch our beta-testing program, but the release date of a global pandemic came a little sooner than ours, putting our sleep-enhancing dreams to an end. However, I got a fun ride into the entrepreneurial world, and valuable hands-on experience with signal processing and tES.

Our headset was built to easily fit into anyone's nighttime routine. Our users could put it on before brushing their teeth or reading a book and start their tailored stimulation session with a simple tap on the Cogna app. The headset's electrodes were designed to deliver a slow alternating current to the prefrontal cortex for 20 minutes to help the brain transition to sleepier states of activity.
