Limitations

The complexity of manufacturing these fibers might be a barrier for some design projects. The cost and scalability of production could also be a concern.

Reliability & validity

The study's validity is supported by the direct comparison to biological somatosensation and the demonstration in functional robotic tasks. Reliability would be assessed through repeated trials and consistent sensor readings under varying conditions.

Think critically
