Peri wearable unveiled at CES 2026 to monitor perimenopause symptoms

Peri, a wearable designed to monitor perimenopausal symptoms, was on display at CES 2026 and is being promoted as one of the first devices aimed specifically at people in the perimenopause transition; the device is listed at $449. Peri is described by the company as a nonintrusive sensor that "attaches near the stomach" with no needles involved, and ZDNET's reporter noted it is similarly sized to a continuous glucose monitor and less flexible in build.

The package includes four sensors—PPG for blood flow, an accelerometer for movement, EDA for skin electricity, and a temperature sensor—and the device tracks metrics such as body temperature, sleep, and cycle information. The company says the device records biomarkers for around seven to 10 days before requiring a recharge and uses a custom algorithm and AI-powered analytics that combine multiple data metrics to detect and predict symptoms like hot flashes, night sweats, anxiety, and sleep pattern changes.

Symptoms are logged alongside users' menstrual-cycle information, and the system can document hormone therapy treatment journeys. Peri's app home page shows sleep timing, an anxiety score, activity level, cycle information, daily/weekly/longitudinal insights, and a journal feature.

The device is aimed at addressing what IdentifyHer's founders describe as a gap in symptom data for perimenopause. "Perimenopause is treated like a mystery or an inevitability that women simply have to 'power through.' We reject this.
