New Sensor Detects Stress via Sweat and Saliva
Scientists in Hyderabad have created a special sensor that can measure stress levels from sweat and saliva.
This sensor is flexible and can be worn on the body, making it easy to use anywhere.
It detects a hormone called cortisol, which the body releases when stressed.
The sensor uses tiny gold particles and special antibodies to accurately measure cortisol levels.
It can work for about a month and gives reliable results.
This new technology could help people monitor their stress levels regularly, especially those who can't easily visit a doctor.
Researchers at BITS Pilani, Hyderabad, developed a flexible biosensor to detect cortisol from sweat and saliva in real time.
The sensor is designed for non-invasive, real-time monitoring of stress levels without the need for blood sampling or lab visits.
Cortisol, a stress hormone, is linked to mental health conditions, heart disease, and immune problems.
The sensor uses gold nanoparticles and cortisol-specific antibodies for accurate detection and is connected to a microfluidic system for controlled analysis of sweat.
The device is stable for nearly a month and can be integrated with wearable electronics for everyday use.
