Tactile sensors are the cornerstone of modern technology development by mimicking human tactile perception and providing precise diverse mechanical feedback for cutting-edge fields such as robotics, medical equipment, virtual reality. However, current research predominantly concentrates on monitoring normal forces. How to accurately recognize decouple multidirectional force pairs remains a challenge. To this end, we design sensor modifying cuprous oxide (Cu2O) surface zinc nanorods (ZnO NRs) arrays integrating it with transverse force-to-vertical conversion structure. As result, modification boosts piezoelectric output ZnO sensitivity 17.25 nA MPa-1, which is about 3 times higher that pure ZnO. The mechanism underlying enhancement illustrated from perspective surface-engineered heterojunction. On basis, ability detect forces verified prototype, can monitor in 12 directions over 360° range. This work provides new strategy designing sensors, showing broad application prospect human-machine interaction beyond.
