Computers are getting smaller and smaller, just as current cell phones offer computing power similar to that of a laptop. And the trend toward miniaturization continues. Smart dust applications (tiny microelectronic devices), such as biocompatible sensor systems in the body, demand computers and batteries smaller than a dust mote. So far, this development has been hindered by two main factors: lack of on-chip power sources for operation anytime and anywhere and difficulties in producing integrable...
