Precision sensors: an innovative future for agriculture

In the summer of 2022, growers in North Carolina were alarmed to find a new variant of the Tomato Spotted Wilt Virus (TSWV). Transmitted by insects called thrips and resistant to existing treatments, TSWV is difficult to eliminate and can ruin an entire crop. With one of the widest ranges among plant diseases, it also…

NC State researchers use machine learning to create a fabric-based touch sensor

A new study from NC State University combines three-dimensional embroidery techniques with machine learning to create a fabric-based sensor that can control electronic devices through touch. As the field of wearable electronics gains more interest and new functions are added to clothing, an embroidery-based sensor or “button” capable of controlling those functions becomes increasingly important. Integrated…
