• Although much effort has been put in the studies of weak in vivo microscale movements due to its importance, the real‐time, long‐time, and accurate monitoring is still a great challenge because of the complexity of the in vivo environment. Here, a new type of mechanically asymmetrical triboelectric nanogenerator with ultrashort working distance and high anti‐interference ability is developed to accurately and real‐timely monitor the microscopically weak movement of intestinal motility at low frequencies even around 0.3 Hz. The intestinal status after the glucose absorption, and physiological states in different times also have been monitored successfully in the complex in vivo environment with many kinds of interference and noises. This work gives a new self‐powered, long‐time and in vivo technical way for the real‐timely gastrointestinal motility monitoring, and contributes to the detection of every kind of gentle movements in various complex bio‐systems. A new kind of mechanically asymmetrical triboelectric nanogenerator with ultrashort working distance is developed to effectively detect the microscopic movement of intestinal motility in a self‐powered way and successfully monitor the intestinal status in the complex in vivo environment.
