Smartphone Test Spots Poisoned Water Risk
Researchers have developed a biosensor that attaches to a smartphone and uses bacteria to detect unsafe arsenic levels. The device generates easy-to-interpret patterns similar to volume-bars that display the level of contamination.
Briefs: Materials
A system was developed that can remove radioactive cesium contamination from porous structures such as brick and concrete that are hard to clean, as well as contamination from metal...
Briefs: Semiconductors & ICs
Researchers have developed a hybrid transformer that has the benefit of a full planar transformer design but uses a wire-wound secondary winding to keep the parasitic winding capacitances lower. Alone, planar transformers...
Briefs: Wearables
A continuous-testing device was developed that samples sweat as effectively as blood but in a noninvasive way and over many hours. After examining the use of saliva, tears, and interstitial...
