Dual channel microtensile load cell. (A) Schematic cartoon. Two linear motors moved independently, and generated tensile forces in each compartment of the tissue placed in the clamps. (B) Photograph of apparatus. In each adjacent channel, a linear motor (1) attached to a strain gauge (2) was coupled via a frictionless air bearing (3) through which passed a tensile shaft (4) connected to the specimen clamp (5).
