Wearable Optoelectronics: Outdoor‐Useable Wireless/Battery‐Free Patch‐Type Tissue Oximeter with Radiative Cooling (Adv. Sci. 10/2021)

摘要

In article number 2004885, Young Min Song and co‐workers report a new way to address thermal issue caused in wearable optoelectronics in outdoor by introducing non‐metallic/flexible radiative cooler with sub ambient cooling of 6 °C in daytime. Under sunlight, the conventional wearable device exhibits an inaccurate tissue oxygen saturation (StO2) value of ≈67%, however, the thermally protected wearable device presents reliable StO2 of ≈80%.
