Researchers at The University of Texas at Austin and Texas A&M University have used electronic tattoo (e-tattoo) technology to measure stress levels, by attaching a device to people’s palms (AKA electrodermal activity or EDA sensing). The researchers created a graphene-based e-tattoo that attaches to the palm, is nearly invisible and connects to a smart watch. Image In June 2022, researchers from the same universities also developed a graphene-based electronic tattoo that can be worn on the wrist for hours and deliver continuous blood pressure measurements at an accuracy level exceeding nearly all available options on the market today.
