The academic and industrial attempts to approach prosthetic arms so far have been met with less success than the providers must have hoped for. Far less, in fact so little that we wonder what is going on.

Possibly, design issues are the key to this as however vaguely put, some analytic approach needs to inform better design - but how to really inform better design from issues based on analysis? What is a suitable analysis? If we cannot see any better designs anywhere in practice, real life, then what is the analysis worth? Can we analyze analyses to get a better understanding of what might be going on there?

We might best start with what we know to be true.

Testing myoelectric arm components in general: uncharted territories

Prosthetic arms in general do not usually appear to be tested a lot before getting thrown at the user, which is a statement that I find many examples for (glove may disintegrate all by itself; glove dies after just a few minutes of car washing; bolts never checked for size; etc.).

This is not to say that this is intrinsically bad - no. This is to say that the burden of testing and suffering the associated negative consequences of that also then reside with the user. If - at all - a company finds it unacceptable that users perform the testing and resulting discussions bad in any way, then (and only then) may they wish to consider a different type of product marketing and testing approach.

The question of whether manufacturers of prosthetic components test anything at all, also for skin safety, that question: it now also officially extends to skin electrodes.

As suggested by their ample advertising, a range of "bionic" myoelectric arms are demonstrated and shown around, as being able to sustain bicycle riding. So we have to assume that everyone seems to be of the opinion that it is cool to ride bikes, with, say, wearing an iLimb.

"With the bionic hand people would be like, hey im sorry for your loss. With the hook hand people would be whispering ‘shit man, that guy probably tried to kill someone important in somalia, and got his hand ripped off by an elephant guard’. Whats cooler than that?"

  • So without further ado, I herewith offer you the new virtual online event of Extreme Cyborging.
