Abstract: A novel flexible tactile sensor for sensing the force direction was designed by introducing the concept of structural electrodes on a piezoelectric film. The structural electrodes comprised an elastomeric column and distributed microelectrodes between the column and piezoelectric film. As a periodic small force acts at the elastomeric column, the force is transferred to the piezoelectric film based on the column bending behavior therefore the scale of force can be detected by the output voltages from the distributed electrodes due to the corresponding force state under the column. In addition, two opposite output signals from different sides of the column can differentiate the force direction as the column is bent by external force. The resulting signal for sensing force and its direction depends on the size of column.

Abstract: A pneumatic nozzle for roller coating is revealed. A workpiece to be coated is fixed on a rotating power source of a machine. A high-pressure pneumatic nozzle and a material supply nozzle, both corresponding to the workpiece, are arranged at the machine. The workpiece is driven to rotate by the rotating power source while the material supply nozzle applies coating material to the workpiece and the high-pressure pneumatic nozzle releases high pressure gas. The coating material attached on the surface of the workpiece is pushed by the high pressure gas and spread uniformly on the workpiece by rotating workpiece. Thereby the material is coated smoothly in a non-contact way and the thickness of the coating material is controlled in micron scale. This helps following manufacturing of three-dimensional microstructures on rolls for producing roll dies and increases the practical value.

Abstract: A welding wire feeding device includes a base, a fixing post, a pressing member, a motor, and a conveying mechanism. The pressing member is pivotally connected with a driven wheel. A tension spring is provided between the fixing post and the pressing member. A shaft portion of the motor is pivotally connected with a driving wheel. The conveying mechanism is coupled to the base and has an air hole. The base is formed with a first passage and a second passage connected with a gas cylinder. The length of the conveying tube of the conveying mechanism can be adjusted by pressing. A wire is sandwiched between the driving wheel and the driven wheel through the tension spring. The motor drives the driving wheel to rotate the driven wheel so as to continuously convey the wire; meanwhile, the inert gas can be sent out through the second passage and the conveying mechanism to prevent a workpiece from being oxidized.
