A scientist in Japan has discovered a way to use human muscles to predict weather and help solve problems, much like a computer does. His early findings could shape the future of wearable and medical technology.
Yo Kobayashi, a researcher at the University of Osaka, published a study showing that human muscle tissue may be capable of processing information. His research, released March 20 in the journal IEEE Access, tested how muscle movements could support a new type of computing.
Human tissue used in a new type of computing
The method is based on a concept known as reservoir computing, Human Muscles. Data is sent on this system through many small, connected units that twist and reshape the information differently.
These patterns are then read to identify important signals or make predictions. While this is usually done with computer software, Kobayashi explored how real materials, in this case, human tissue, could serve the same purpose.
Muscle movement reveals useful patterns
Kobayashi tested the idea by asking volunteers to bend their wrists at different angles. He used ultrasound to capture how the muscles changed shape during each movement. These images showed that muscle tissue reacts in complex, layered ways, which can store and carry information over time.
Using this data, he created a simple model to show how muscle movement could support problem-solving tasks. The system passed standard tests, suggesting body tissue could work as a physical tool for processing.
Kobayashi said muscle tissue doesn’t just respond in a straight line. It has memory-like qualities and reacts differently based on past movements. This makes it useful for interpreting patterns.
One analogy used to explain this type of computing is the “bucket of water” model. Imagine tanks of water linked by pipes. When you pour water into one tank, it doesn’t just flow in a straight path; it moves in complex ways, affecting other tanks over time.
These water level changes mimic how information moves through a reservoir system. Kobayashi suggests human tissue behaves similarly.
Potential use in wearables and medical devices
Because soft tissue is found throughout the body, Kobayashi believes the approach could be used in wearable devices. A future device might rely on the body to handle some of the workload, improving speed and efficiency. He also sees potential use in medical tools or machines that work closely with the human body.
“This study only performed benchmark tests; hence, it is imperative to determine the applicability of the actual computational process in future scenarios. However, these findings pave the way for successfully exploring human tissue dynamics in a variety of computational tasks and applications,” Kobayashi said.
Outside of wearables, researchers believe the human muscles could help predict complex systems like weather or stock prices, simply by learning from past patterns.
Kobayashi says the work is in early stages, but it highlights how the body’s natural responses could support smarter machines in the years ahead.
