ABSTRACT:
A push-pull force transducer comprising a unitary body formed from a crystalline substrate. The body comprises first and second mounting elements for mounting the force transducer to first and second structures, and first and second force sensing elements connected to the mounting elements. Each force sensing element has first and second ends, a line extending from the second to the first end defining a force sensing axis for the force sensing elements. The force sensing elements are oriented with their force sensing axes parallel to and aligned with one another. The first force sensing element has its first end connected to the second mounting element and its second end connected to the first mounting element. The second force sensing element has its first end connected to the first mounting element and its second end connected to the second mounting element. Also described are embodiments utilizing strain relief flexures and an embodiment featuring a leveraged design.
