The outstanding properties of graphene have initiated myriads of research and development;yet, its economic impact is hamperedby the difficulties encountered in production and practical application. Recently discovered laser-induced graphene is generated bya simple printing process on flexible and lightweight polyimide films. Exploiting the electrical features and mechanical pliability ofLIG on polyimide, we developed wearable resistive bending sensors that pave the way for many cost-effective measurementsystems. The versatile sensors we describe can be utilized in a wide range of configurations, including measurement of force,deflection, and curvature. The deflection induced by different forces and speeds is effectively sensed through a resistancemeasurement, exploiting the piezoresistance of the printed graphene electrodes. The LIG sensors possess an outstanding range forstrain measurements reaching >10% A double-sided electrode concept was developed by printing the same electrodes on bothsides of the film and employing difference measurements. This provided a large bidirectional bending response combined withtemperature compensation. Versatility in geometry and a simple fabrication process enable the detection of a wide range of flowspeeds, forces, and deflections. The sensor response can be easily tuned by geometrical parameters of the bending sensors and theLIG electrodes. As a wearable device, LIG bending sensors were used for tracking body movements. For underwater operation,PDMS-coated LIG bending sensors were integrated with ultra-low power aquatic tags and utilized in underwater animal speedmonitoring applications, and a recording of the surface current velocity on a coral reef in the Red Sea.

Illicit and pharmaceutical drugs are considered to be emerging contaminants of concern,and much research effort has gone into assessing their occurrence in ***,little information exists on their presence in treated sludge or *** this study,we examined sludge and biosolids from a large metropolitan wastewater treatment plant(WWTP)in Australia to determine the occurrence of five drugs of abuse,including benzoylecgonine as indicator of cocaine consumption,methamphetamine and 3,4-methylenedioxy methamphetamine(MDMA)as representative illicit stimulants,and codeine and morphine as pharmaceuticals with potential environmental *** samples were solid-phase extracted and analyzed by liquid chromatography–tandem mass spectrometry(LC–MS/MS).Benzoylecgonine and MDMA were present in raw sludge but were notably degraded during solids treatment processes,and were not detected in the dewatered sludge(after treatment)or in ***,codeine,and morphine were detected in all biosolids samples at mean concentrations of 20–50 lg kg^-*** presence of these three drugs in biosolids shows that these compounds are relatively stable in the solids and in soil,and can persist in biosolids for at least several years.A simple environmental risk assessment based on estimated risk quotients(RQs)for these compounds indicated that the potential environmental risks associated with the land application of biosolids are very low at typical Australian biosolids application rates.
