This work reports the complete theoretical modeling, simulation, and experimental characterization of a self‐powered cursor based on triboelectric nanogenerator (TENG). The self‐powered cursor is made of liquid‐metal and polydimethylsiloxane (PDMS) mixture that deforms and contacts with different sensing electrodes under different applied force. The self‐powered cursor has the capability of simultaneously detecting normal force (0–25 N) and shear force direction (0°–360°) for the first time. The normal force sensing is characterized by open‐circuit voltage, charge, and current with the sensitivity of 0.131 V N⁻¹, 0.048 nC N⁻¹, and 0.175 nA N⁻¹, respectively. The shear force direction detection can achieve a direction resolution of 15°. Because of the high output voltage and low internal impedance, the self‐powered cursor is readily compatible with commercial portable circuits without the requirement of specified bulky high‐impedance instruments to detect the output voltage. Demonstration of the self‐powered cursor as a triggering signal to drive a small vehicle is successfully realized by directly detecting the output voltage without any periphery signal processing circuits. The robust structure, stable output performance, and self‐powered sensing property enable the self‐powered cursor as an ideal human machine interface towards batteryless, energy saving, and environmentally friendly applications.

使用摩擦电机制的自供电光标

这项工作报告了基于摩擦电纳米发电机（TENG）的自供电光标的完整理论建模，仿真和实验表征。自供电光标是由液态金属和聚二甲基硅氧烷（PDMS）混合物制成的，它们在不同的作用力下会变形并与不同的感应电极接触。自供电光标具有首次同时检测法向力（0–25 N）和剪切力方向（0°–360°）的能力。法向力感测的特征在于，开路电压，电荷和电流随0.131 VN的灵敏度^-1，0.048 NCÑ ^-1，和0.175 nA的Ñ ^-1， 分别。剪切力方向检测可以实现15°的方向分辨率。由于输出电压高且内部阻抗低，因此自供电光标可轻松与商用便携式电路兼容，而无需使用指定的笨重的高阻抗仪器来检测输出电压。通过直接检测输出电压而无需任何外围信号处理电路，就可以成功实现自供电光标作为驱动小型车辆的触发信号的演示。坚固的结构，稳定的输出性能和自供电的感应特性使自供电的光标成为实现无电池，节能和环保应用的理想人机界面。
