Today, 90 percent of automation sensors are binary proximity detectors. Besides capacitive and optical types, inductive proximity sensors are essential for industrial applications. Compared to their mechanical counterparts, they offer almost ideal properties as contact-free and wear-free ... Mehr lesen
利用压电阻抗法获取压电材料随监测结构不同损伤状态而变化的阻抗信号来实现监测的目的，一般将压电材料粘贴于监测结构表面或者内嵌入结构，当施加交变电场于压电材料时，电场会激发压电材料产生相应的机械振动，从而对被监测的结构施加激励，不同健康状态的结构会产生不同的机械振动，而相应的振动信号会由于正压电效应而反应在压电材料的电阻抗变化中。因此通过提取不同应力状态时阻抗信号中结构的谐振或压电材料的谐振信息，建立特征频率与力载荷之间的关系，从而实现结构应力监测的目的。 模型采用四分之一对称模型，将压电片嵌于铝板之中。确定压电片的压电柔度矩阵、压电应变矩阵、相对介电矩阵 ... Mehr lesen
Electrical stimulation of the brain involves the application of currents delivered through scalp electrodes to modulate brain activity, known as Transcranial Current Stimulation (TCS). A critical factor for TCS efficacy and safety is the “spatial focality” of induced neuronal modulation. ... Mehr lesen
