Fully Stretchable, Wireless, Skin-Conformal Bioelectronics for Continuous Stress Monitoring in Daily Life

Abstract

An exemplary embodiment of the present disclosure provides a method of determining stress levels in a user comprising: receiving galvanic skin response (GSR) measurements by a wearable sensor on the user over a period of time; receiving temperature measurements by the wearable sensor on the user over the period of time; determining changes in the temperature over a predetermined threshold in the temperature measurements over the period of time; calibrating the GSR measurements based on the determined changes in temperature over the predetermined threshold; calculating a stress level of the user based on the calibrated GSR measurements; and generating an output indicative of the calculated stress level.

AI Technical Summary

Benefits of technology

The present patent provides a method and device for measuring and indicating stress levels in a user through the use of galvanic skin response (GSR) and temperature measurements. The method involves calibrating GSR measurements based on changes in temperature, calculating the stress level of the user based on the calibrated GSR measurements, and displaying the calculated stress level on the wearable sensor or a remote device. The device can be a wearable sensor or a smartphone. The technical effect of this patent is to provide a reliable and non-invasive method for measuring and indicating stress levels in a user through the use of GSR and temperature measurements.

Problems solved by technology

These, however, are purely subjective.

Although this MRI technique is a quantitative measure, it has major limitations due to its high cost, dicrete measurement, and limited availability.

Such measurement system has limitations of device locations that can bother daily activities and motion artifacts caused by wires and gels.

However, these devices still rely on rigid metals and multiple electronic components with bulky plastic packaging and prevent the conformal skin-to-device interface, resulting in the use of a tightly worn band or aggressive tapes.

Further, these devices still fail to provide accurate measurements of stress levels experienced by users.
