Researchers have discovered a simple, cost-effective, and accurate new method for equipping self-driving cars with the tools needed to perceive 3D objects in their path.
A multidisciplinary team of researchers has developed an innovative wearable device capable of analyzing human sweat to monitor cortisol levels—the primary hormone associated with physiological stress—in real time. The solution is built around a compact microfluidic platform that efficiently captures and channels sweat from the skin, enabling continuous, non-invasive sampling without disrupting the wearer’s daily activities.At the core of the device is a highly selective cortisol-specific antibody sensor, designed to accurately quantify cortisol concentrations as they fluctuate throughout the day. By integrating biochemical sensing with wearable technology, the system delivers near–real-time insights into the body’s stress response, eliminating the need for blood draws or laboratory-based analysis.
The device has undergone extensive validation in both controlled laboratory environments and real-world use cases, demonstrating consistent performance, reliability, and sensitivity across varying conditions. Test results indicate strong correlation with established cortisol measurement methods, positioning the technology as a credible and practical tool for continuous stress monitoring.
Researchers believe this advancement has broad potential applications across multiple domains. In athletics, it could help optimize training loads, prevent overtraining, and support recovery strategies. In occupational and high-performance environments, it may enable proactive stress management and performance optimization. Additionally, in mental health and wellness contexts, the technology could support more personalized treatment approaches by providing objective, data-driven insights into stress patterns over time. Overall, this wearable platform represents a significant step forward in real-time, non-invasive physiological monitoring.
