Birmingham engineers have developed tiny engines only a few
millimetres wide, that could soon replace a standard battery.
Lead by Dr. Kyle Jiang, investigators at the
University's School of Engineering are the first to manufacture
these engines in a durable, heat resistant material such as a
ceramic or silicon carbide.
As a result, these micro-engines will have
over 300 times more energy than an ordinary battery and are much
lighter and smaller.
power-supplying machines could be used to charge mobile phones and
lap top computers in a matter of seconds and could also be used for
a range of other applications such as micro-factories, tiny
"labs-on-a-chip" that will be able to make drugs,
chemicals or small mechanical components.
