Sleep breaks 20 to 30 times a night without fully waking you. DUSQ is a behind-the-ear wearable that watches skin conductance for those disruptions and answers each one with a short vestibular and vagus-nerve pulse, aiming to pull you back into deep sleep before you surface.
The company reports 31% more deep sleep and 22% fewer awakenings within two weeks of use, and says it has been manufacturing and shipping units for a year. 4,329 backers put in $1,232,557. Retail listed at $499.
Who should buy: people who sleep eight hours and wake up wrecked. Who shouldn't: anyone expecting a medical device — DUSQ calls itself a wellness product.
