Claims6
A thermoelastic actuator that comprises an expansive element of a material or combinations of materials selected from a group consisting of silicides and carbides of titanium, having
- a resistivity between 0.1 μΩm and 10.0 μΩm and being
- chemically inert in air.
A thermoelastic actuator that comprises an expansive element of a material or combinations of materials selected from consisting of borides, silicides, carbides and nitrides of tantalum, molybdenum, niobium, chromium, tungsten, vanadium, and zirconium, having
- a resistivity between 0.1 μΩm and 10.0 μΩm and being
- chemically inert in air.
A thermoelastic actuator that comprises an expansive element of an alloy material or combinations of alloy materials selected from the consisting of borides, silicides, carbides and nitrides of titanium, tantalum, molybdenum, niobium, chromium, tungsten, vanadium, and zirconium, having
- a resistivity between 0.1 μΩm and 10.0 μΩm and being
- chemically inert in air.
