CES 2026 health tech trends: Why your bodily fluids are the next big data source

Forget the flashy screens and transparent TVs. The real stars of CES 2026 aren't on your wrist—they're in your bathroom. According to The Verge, the wellness industry is pivoting from passive monitoring to invasive but hyper-accurate analysis of urine, blood, sweat, and saliva.

CES 2026 health tech trends: The shift to bio-fluids

For years, the industry focused on what you could watch from the outside: steps, heart rate, and sleep cycles. But at CES 2026, companies like Mira are proving that the most valuable health data lies inside our bodies. Mira's hormone testing kit requires users to provide urine samples, which are then analyzed to provide precise biological insights that a standard smartwatch simply can't match.

This isn't just about specialized niche products. The industry is reaching ground zero of a new wellness era. While some attendees groaned at the mention of 'bodily fluids,' insiders weren't surprised. It's the logical next step for a market that has already saturated the 'optical sensor' category.

From tracking to diagnosing

The transition to fluid-based tech represents a significant leap in data fidelity. Instead of estimating stress through skin conductance, new devices aim to measure cortisol levels directly. Instead of guessing metabolic health, they're looking at blood glucose and lactic acid in real-time. It's a move toward bringing the pathology lab into the smart home.
