Ultra‐Sensitive Bio‐Polymer Iontronic Sensors for Object Recognition from Tactile Feedback

Supramolecular polymer gels show promise for use in batteries, supercapacitors, and multifunctional sensors. However, their poor stiffness ionic conductivity hinder large-scale utilization. Here, a cellulose-based supramolecular bio-polymer gel (SBPG) with high exceptional is reported. These properties have been translated into proof-of-concept iontronic pressure sensors an ultra-high sensitivity of 1 475 000 kPa−1. The technological potential demonstrated via fabrication prototype smart glove using only eight based on this novel gel. Smart 90% classification accuracy object recognition are tactile feedback algorithm.
