“…The rapid growth of the Internet of things (IoT), wearable electronics, and autonomous systems has increased the demand for the use of multiple sensors to achieve real-time control and acquisition of useful information. Among the various types of sensors, inertial motion sensors are in high demand because of the emerging fields of robotics control, [1][2][3] computer gaming, [4][5] automotives, [6][7][8] sports, [9][10][11][12][13] activity Moreover, the reported sensors are not perfectly applicable to arbitrary parameter detection (all direction sensing is not fully realized), have limited functionalities, and are confined to specific motion conditions (only linear, rotational, or tilting motion sensing capability). Thus, realizing a completely self-powered arbitrary motion sensing system with full functionalities on a single device with adequate accuracy is a major challenge.…”

Self‐powered arbitrary motion sensors are in high demand in the field of autonomous controlled systems. In this work, a magnetic repulsion‐assisted self‐powered motion sensor is integrated with a hybrid nanogenerator (MRSMS–HNG) as a battery‐less arbitrary motion sensing system. The proposed device can efficiently detect the motion parameters of a moving object along any arbitrary direction and simultaneously convert low frequency (<5 Hz) vibrations into useful electricity. The MRSMS–HNG consists of a central magnet for the electromagnetic (EMG)–triboelectric (TENG) nanogenerator and four side magnets for motion sensors. Because all the magnets are aligned in the same magnetization direction, the repulsive force owing to the movement of the central magnet actuates the side magnets to achieve self‐powered arbitrary motion sensing. These self‐powered motion sensors exhibit a high sensitivity of 981.33 mV g−1 under linear motion excitation and have a tilting angle sensitivity of 9.83 mV deg−1. The proposed device can deliver peak powers of 27 mW and 56 µW from the EMG and TENG, respectively. By integrating the self‐powered motion sensors and hybrid nanogenerator on a single device, real‐time wireless transmission of motion sensor data to a smartphone is successfully demonstrated, thus realizing a battery‐less arbitrary motion‐sensing system for future autonomous control applications.
