New design framework creates self-folding paper wearable sensors tailored to body shapes

Wearable sensors, such as wristbands, rings and adhesive patches, are becoming increasingly common for health care monitoring, fitness tracking and human-machine interaction. While most wearable devices are made from flexible polymers or textiles, paper-based sensors are emerging as cheaper and more sustainable alternatives. Such sensors could be used for applications such as medical diagnosis or detecting contaminants and toxins and could be safely discarded after use.
