Engineers have built the first dust-sized, wireless sensors that can be implanted in the body, bringing closer the day when a Fitbit-like device could monitor internal nerves, muscles or organs in real time.
An international team has introduced a three-dimensional X-ray diffraction technique for determining crystallographic texture - the preferred orientation of the little crystals in a solid - with previously unattainable spatial resolution.
The advanced technologies designed by researchers working on the SURFUND project go beyond the current state-of-the-art techniques in metrology, the science of measurements applied to manufacturing and other industrial processes.
Engineers have created high-performance, micro-scale solar cells that outshine comparable devices in key performance measures. The miniature solar panels could power myriad personal devices -- wearable medical sensors, smartwatches, even autofocusing contact lenses.
