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 degrees-360 degrees) 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 degrees. 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.
