Scientists have presented a non-contact method for detecting the state of charge and any defects in lithium-ion batteries. Rechargeable batteries are at the heart of many new technologies involving, ...

To develop novel confocal fibre-optic laser method (CFOLM) for accurate and objective measuring of the dioptric power of both positive and negative intraocular lenses (IOLs). The CFOLM principle of ...

Subtle abnormalities in kidney function—even within the range considered normal—may help identify people at risk of ...

Maybe the most common applications for very-low-value resistors (i.e., milliohms (mΩ) and below) are current-controlling circuits, where their low value reduces power losses. For these applications, a ...

Noninvasive methods of measuring blood glucose levels have demonstrated promise in early trials and could be potential replacements for glucose monitoring in the future, according to a review. A ...

Vision-based structural health monitoring methods offer non-contact, full-field vibration measurement, reducing costs by ...

Large-aperture interferometers are important in the manufacturing and measurement of large-aperture optical elements, which play critical roles in the fields of optical precision manufacturing and ...
