Caltech Develops 'Electronic Skin' to Monitor Stress

The CARES device uses machine learning to provide real-time stress-level insights.

Caltech researchers have developed a wearable device called CARES (consolidated artificial-intelligence-reinforced electronic skin) that continuously monitors nine different markers to characterize a stress response.
The device is a slim, adhesive gadget worn on the wrist, allowing individuals to carry out their routine daily activities with minimal disruption during testing.
CARES integrates sweat sensors with sensors that record pulse waveforms, skin temperature, and galvanic skin response, physiological signals that indicate stress in predictable ways.
New materials have been introduced to the device to enhance sensor stability during long-term operation.
The device uses machine learning to interpret the complex data it collects, providing real-time stress-level insights.
