Scientists have created an army of microscopic robots, each smaller than the width of a human hair, that can be injected into the body to wage war on disease.

• The new Micro-bots could monitor nerve impulses in the heart or brain or even deliver drugs directly into organs, according to scientists from Cornell University who created the machines.

• The minute four-legged machines will enter the body via a hypodermic needle and travel through human tissue and blood using four electrochemical actuators that function as 'legs'.

• The micro-bots are powered by solar cells and are made using a technique called photovoltaics - used at a larger scale in solar energy panels.

• The legs are wired to several 'photovoltaic' patches on the robots central chassis and when an operator shines a laser on them they 'bend and unbend'.

• This can alternate between bending the front and back legs by aiming the light on different patches - propelling the robot.

• The researchers control the robots by flashing laser pulses at different cells - each of which charges up a separate set of legs.

• They can survive the harshest of conditions, according to the researchers that designed the technology. The limbs of the microbots are also incredibly strong. Each robot's body is 1,000 times thicker and 8,000 times heavier than each leg.

• As they are manufactured from silicon, sensors will be able to measure temperature and electrical pulses.
