Biomimetic sensor technology is always superior to existing human technologies.
Integrated sensor-actuators with exciting functionalities, such as action self-sensing, position posture or active sensing, are promising for applications in biomedical device, human-machine interaction, intelligent self-protection devices, and humanoid robots. Despite recent progress, it remains challenging to achieve a macroscopical integrated sensor-actuator material system microstructures. To address this critical challenge, 4D printing bioinspired microstructure strategy is reported...
