By analyzing human tissue, Yo Kobayashi—the lone author on the paper—discovered that the soft biological structures possessed many of the properties that would make them particularly adept at this type of computing. Then, Kobayashi took various ultrasound images to capture all of the miniscule muscle deformations in the wrist, which allowed him to construct a “biophysical reservoir” for data processing. Kobayashi benchmarked his breakthrough by testing the human tissue using complicated nonlinear equations, and the model using the biophysical reservoir turned out to be more accurate than a model that used standard linear regression. “In the future, it may be possible to use our own tissue as a convenient computational resource. Since soft tissue is present throughout the body, a wearable device could delegate calculations to the tissue, enhancing performance.”So, could our bodies one day be computational devices?
