3D-Printed Cellulose Hydrogel Keeps Wearable Sensors Working at -13°F

3D-printed cellulose hydrogel keeps wearable sensors working at -13°F

Wearable sensors could become more reliable in freezing conditions with a new cellulose-based hydrogel that continued detecting movement after being exposed to -13°F for seven days. Researchers developed the flexible material from cotton pulp cellulose, turning an abundant renewable material into an electrically conductive hydrogel. The approach is designed to address a basic problem with conventional hydrogel sensors: water inside them can free…

3D-Printed Cellulose Hydrogel Keeps Wearable Sensors Flexible Below

Flexible wearable electronics may soon become far less vulnerable to winter conditions, thanks to a cellulose-based hydrogel that continues to conduct ionic signals even after prolonged exposure to subzero temperatures. Researchers from Southwest Jiaotong University have developed a transparent, flexible and 3D-printable material that resists freezing, retains mechanical strength and can detect human motion under […]
