Washington. American and Canadian scientists developed a device that uses human movement to generate energy. The device that is located in the knee has proven to achieve the production of approximately 5 watts, enough power to operate two computers or 10 cell phones.The researchers say that this is an important advance because it can be put at the service of medicine to, for example, promote robotic prostheses, extend the useful life of the batteries of insulin pumps implanted in the body; it can also be useful in remote regions to generate emergency power or lighten the load on soldiers and campers.
The energy harnessed by human movement has long been a goal of scientists, previously tests were made with which no significant progress had been made, because not enough energy was generated and the devices were heavy for those who transported them.
