SEOULTECH Researchers Make Auxetic 3D Printed Pressure Sensors for Wearables

SEOULTECH researchers from Seoul National University of Science and Technology have developed auxetic 3D printed pressure sensors for wearables and prosthetics. These sensors, made using vat polymerization printing of elastomeric materials, have a negative Poisson’s ratio and are more sensitive than traditional sensors. The team's research could have applications in gait monitoring, prosthetics, wearables, and medical monitoring. By integrating these sensors into smart insoles, robotic hands, and wearable health monitoring systems, they aim to improve comfort and performance in various applications. The use of digital light processing-based 3D printing allows for precise customization of sensor performance without changing the base material, offering scalability and compatibility with different transduction modes.
