Fuel cells are electrochemical devices which produce electricity from renewable and clean resources, such as hydrogen. Their large-scale exploitation is expected to impact positively our approach to use electric energy in vehicles, buildings and other portable/stationary applications. ... Read More
We present a modeling software package developed at Ostendo Technologies for analysis and design of semiconductor laser and light-emitting diodes. The current database of material parameters supports complete group of III-Nitride alloys used in visible spectrum applications and can be ... Read More
In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on ... Read More
Neuromodulation is the use of electromagnetic fields to modulate the human nervous system, typically to treat neurological disorders. Electroceuticals is an ambitious program to modulate any nerve, anywhere, anytime, for any reason — to treat disease, disorders, and enhance or interface ... Read More
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 ... Read More
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. ... Read More
