| 1 | Wearable multifunctional printed graphene sensors显示文摘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. | Altynay Kaidarova Mohammed Asadullah Khan Marco Marengo Liam Swanepoel Alexander Przybysz Cobus Muller Andreas Fahlman Ulrich Buttner Nathan R.Geraldi Rory P.Wilson Carlos M.Duarte Jurgen Kosel | 2019 | npj Flexible Electronics2019，3，1： | 2 |
| 2 | Defect passivation by nontoxic biomaterial yields 21% efficiency perovskite solar cells显示文摘Defect passivation is one of the most important strategies to boost both the efficiency and stability of perovskite solar cells(PSCs).Here,nontoxic and sustainable forest-based biomaterial,betulin,is first introduced into perovskites.The experiments and calculations reveal that betulin can effectively passivate the uncoordinated lead ions in perovskites via sharing the lone pair electrons of hydroxyl group,promoting charge transport.As a result,the power conversion efficiencies of the p-i-n planar PSCs remarkably increase from 19.14%to 21.15%,with the improvement of other parameters.The hydrogen bonds of betulin lock methylamine and halogen ions along the grain boundaries and on the film surface and thus suppress ion migration,further stabilizing perovskite crystal structures.These positive effects enable the PSCs to maintain 90%of the initial efficiency after 30 days in ambient air with 60%±5%relative humidity,75%after 300 h aging at 85℃,and 55%after 250 h light soaking,respectively.This work opens a new pathway for using nontoxic and low-cost biomaterials from forest to make highly efficient and stable PSCs. | Shaobing Xiong Tianyu Hao Yuyun Sun Jianming Yang Ruru Ma Jiulong Wang Shijing Gong Xianjie Liu Liming Ding Mats Fahlman Qinye Bao | 2021 | Journal of Energy Chemistry2021，30，4： | 2 |
