主　　题：2D materials contact resistance dendritic bilayer MoS_(2) flexible strain sensor 

摘      要：Two-dimensional transition metal dichalcogenides(2D TMDs)are promising as sensing materials for flexible electronics and wearable systems in artificial intelligence,tele-medicine,and internet of things(IoT).Currently,the study of 2D TMDs-based flexible strain sensors mainly focuses on improving the performance of sensitivity,response,detection resolution,cyclic stability,and so *** are few reports on power consumption despite that it is of significant importance for wearable electronic *** is still challenging to effectively reduce the power consumption for prolonging the endurance of electronic ***,we propose a novel approach to realize ultra-low power consumption strain sensors by reducing the contact resistance between metal electrodes and 2D MoS_(2).A dendritic bilayer MoS_(2) has been designed and synthesized by a modified CVD ***-area edge contact has been introduced in the dendritic MoS_(2),resulting in decreased the contact resistance *** contact resistance can be down to 5.4 kΩμm,which is two orders of magnitude lower than the conventional MoS_(2) *** fabricate a flexible strain sensor,exhibiting superior sensitivity in detecting strains with high resolution(0.04%)and an ultra-low power consumption(33.0 pW).This study paves the way for future wearable and flexible sensing electronics with high sensitivity and ultra-low power consumption.
