Researchers in Iceland have developed bionic legs that<br />can be controlled by a person’s thoughts alone. It<br />involves surgically implanting myoelectric sensors<br />(IMES) into a person’s residual muscle tissue to<br />measure and interpret signals travelling between the<br />brain and its nerve-endings. The implanted sensors send<br />wireless signals to the artificial limb’s built-in computer,<br />enabling subconscious, real-time control and faster,<br />more natural responses and movements.<br />This new mindcontrolled technology developed by Ossur for<br />lower-limb prosthetics is designed to be compatible with its line of bionic feet, knees and legs. A coiled-wire receiver inside the<br />prosthesis’ cup picks up impulses and transmits these<br />wirelessly to the robotic limb.<br />

A computer made out of water droplets</h3>
An assistant professor of bioengineering at Stanford University, the USA, Prof. Manu Prakash has created a water based computer. He, along with his two students, has devised a system with the help of tiny water droplets that could work as a computer clock. For this, water droplets are trapped in a magnetic field. When applied to a flipped magnetic field, these form a precise motion in a fixed direction. According to the team, the system can be made smaller by controlling millions of droplets with the help of the magnetic field, so that it can perform a higher number of operations on a single chip. According to Prakash, this computer founds its application in biology and chemistry by converting the computer into a high-throughput laboratory.
