Design of micro force sensor based on PVDF
, 2015 目前微装配领域还没有可靠的亚微牛(sub-μN)分辨率的传感器。针对这一实际难题,设计了一个基于PVDF的微力传感器,使其能够提供高精度、高可靠性的微小力测量。首先基于压电效应和材料力学中悬臂梁结构,设计了PVDF传感器悬臂梁模型。其次由于PVDF产生的电荷很少且为sub-pc量级,设计了一个信号调理电路把电荷量转换为电压量。最后在New Focus公司生产的3D智能运动平台上进行实验,实验结果表明,所设计的PVDF传感器分辨力可以达到在sub-μN范围 ...

Plasmonic Enhancement of Fluorescence and Protein Dynamics in Living Mammalian Cells
Advanced Materials, EarlyView.This study demonstrates plasmonic enhancement of the function of fluorescent voltage sensing proteins (genetically encoded voltage indicators, (GEVIs), QuasAr6) in live mammalian cells. Coupling to plasmonic nanoparticles does not just increase fluorescence, but influences the protein photocycle, creating a hybrid sensor with its response speed to ...
