Abstract
Devices, systems, and methods including sensors that can be used in prostheses, including powered prostheses are described herein. An example force-moment sensor includes a first block having a first curved surface; a second block having a second curved surface; an elastic element arranged between the first block and the second block; and at least one sensing element configured to measure a deflection of the elastic element.
Claims18
A force-moment sensor for a prosthetic joint, comprising:
- a first block having a first curved surface;
- a second block having a second curved surface;
- an elastic element arranged between the first block and the second block;
- and
- at least one sensing element configured to measure a deflection of the elastic element;
- wherein at least one of the first curved surface and the second curved surface is configured to bend the elastic element when a force or a moment of force is applied to the force-moment sensor.

A system comprising:
- a prosthetic device comprising a first portion, a second portion, and a joint, the first portion and the second portion being joined by the joint;
- and
- a force-moment sensor arranged in the joint, the force-moment sensor comprising:
- a first block having a first curved surface;
- a second block having a second curved surface;
- an elastic element arranged between the first block and the second block;
- and
- at least one sensing element configured to measure a deflection of the elastic element-;
- wherein the first block defines a first end and a second end opposite the first end, the first end comprising a first flat edge, wherein the second block comprises a third end and a fourth end opposite the third end, the third end comprising a second flat edge, and the first and second blocks are arranged so that the first end of the first block is adjacent to the fourth end of the second block;
- and wherein the elastic element is fixedly attached to the first end of the first block and fixedly attached to the third end of the second block.
