Sudoris: Next-Generation Sweat Biometric Wearable & Hydration Patch

Sudoris is building a non-invasive biometric wearable and sweat patch that continuously monitors sweat flow rate and electrolyte concentration to deliver real-time hydration readiness scores, cramp risk assessments, and predictive hydration strategies for athletes.

What is sweat rate?

Sweat rate is the volume of sweat produced per hour during exercise, typically ranging from 0.5-2.5 liters depending on intensity, environment, and individual physiology.

Why do athletes cramp?

According to the American College of Sports Medicine (2024), a 2% loss in body weight from sweat reduces endurance performance by up to 20%. Muscle cramps during exercise are primarily caused by dehydration and sodium depletion over extended periods of strain.

What are sweat patches and hydration biosensors?

Sweat patches (or wearable hydration biosensors) are microfluidic devices worn on the skin that capture and analyze sweat during exercise. Unlike generalized smartwatches, sweat sensors track exact sodium loss, potassium levels, and overall fluid loss. Sudoris represents the next evolution of this technology, moving beyond one-time-use consumable patches into a comprehensive, real-time performance platform.

Best wearable for preventing cramps

The best wearable for preventing cramps tracks both fluid loss (sweat rate) and electrolyte depletion (sodium concentration). Sudoris integrates these dual metrics to alert athletes before they cross the critical dehydration threshold that triggers muscle cramping.
