IEEE Spectrum: Radios With Micromachined Resonators. It’s likely that better mechanical components, and the cognitive-radio techniques they enable, will usher in the next wave of mobile telephony by giving our cellphones access to much more spectrum. These phones will operate in multiple bands, provide greater data throughput, and minimize if not eliminate the [...]

One of the major problems for micromachines, much less nanomachines, is wear. The phenomenon of stiction combines the two worst aspects of surface-to-surface interaction — a high coefficient of friction and a locally-generated high applied force — to cause enormous problems. At the very smallest scale, once we gain complete control over atomic configuration, superlubricity [...]

Nanotech contributions to the development of medical science now include devices that can decipher the chemical communications among individual cells. A new microfluidic device called a multi-trap nanophysiometer promises to be particularly useful in elucidating the communications among individual cells of the immune system, and perhaps eventually revealing what goes wrong during the immune system’s [...]
