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