A conductive nonwoven fabric includes: a nonwoven fabric; and a plating portion having a conductive metal and covering a fiber of the nonwoven fabric. A value obtained by dividing an electric resistance value at an intermediate layer of the conductive nonwoven fabric by an electric resistance value at a surface layer of the conductive nonwoven fabric is 4.0 or less. The intermediate layer is a layer at an intermediate position in a thickness direction of the conductive nonwoven fabric.

An elastomer piezoelectric element includes a plurality of unit layers disposed along a thickness direction of the elastomer piezoelectric element. Each of the unit layers includes a sheet-shaped dielectric elastomer dielectric portion, a conductive elastomer electrode partially disposed on a first surface of the dielectric portion, and an insulating elastomer insulated portion that is provided in at least a portion of an area surrounding the electrode and brings a thickness of the unit layer in a portion in which the electrode is not disposed close to a thickness of the unit layer in a portion in which the electrode is disposed.

A joystick assembly is disclosed. In embodiments, the joystick controls a boom and aids in insulating a user from potential electric shock. Handle utilized by the operator may be made of, or at least one surface coated or covered in, material highly-resistant to electric current. The highly-resistant material may also extend to other components such as, a connecting rod, and a mounting base. The highly-resistant components may separate the operator from electrically charged components. As well as separating the operator from potentially electrically charged components, the rod may be received at the base by force measuring sensors, or strain measuring sensors may be attached to the rod. This allows the handle and rod to be stationary and, in embodiments, rigid, and only the applied force to be measured, thus decreasing the number of components needed in the assembly.

A method for manufacturing a connection body, and a method for connecting a component, which can secure conduction reliability by trapping conductive particles even when the bump size is minimized. The method includes a disposing step of disposing a filler-containing film having a filler-aligned layer in which individual independent fillers are aligned in a binder resin layer between a first component having a first electrode and a second component having a second electrode; a temporary fixing step of pressing the first component or the second component to sandwich the filler-aligned layer; and a final compression boding step of further pressing the first component or the second component after the temporary fixing step to connect the first electrode and the second electrode.
