## Abstract

A bi-directional force sensor which includes a first body and a second body. The first body has a first portion and a second portion. The second body also has a first portion and a second portion. The second body interlocks with the first body with the first portion of the second body positioned between the first portion and the second portion of the first body and the second portion of the first body positioned between the first portion and the second portion of the second body. A first sensor is positioned between the first portion of the first body and the first portion of the second body. A second sensor is positioned between the second portion of the first body and the first portion of the second body. This bi-directional force sensor was developed for use in assessing cycling technique.

## Claims

### Claim 1

A bi-directional force sensor, comprising:
a first body having a first portion and a second portion;
a second body having a first portion and a second portion, the second body interlocking with the first body with the first portion of the second body positioned between the first portion and the second portion of the first body and the second portion of the first body positioned between the first portion and the second portion of the second body;
a first sensor positioned between the first portion of the first body and the first portion of the second body; and
a second sensor positioned between the second portion of the first body and the first portion of the second body.

### Claim 2 (depends on 1)

The force sensor of claim 1, wherein the first body and the second body are U shaped.

### Claim 3 (depends on 1)

The force sensor of claim 1, wherein a first mounting on the first portion of the first body and a second mounting on the second portion of the second body.

### Claim 4 (depends on 2)

The force sensor of claim 2, wherein the first mounting is a shoe clip and the second mounting is a bicycle pedal.
