Electrocorticography (ECoG) neural signal recording has been widely used for recording brain electrical signals in brain research and clinical applications for disease diagnostic. In this work, we developed a flexible and re-pluggable ECoG electrode based on chromium-silver-chromium (Cr-Ag-Cr) structure which was deposited on 50 μm thick polymide (PI) foil. This electrode was used in neural signal...
Humidity is a vital physical quantity which is extremely important to production quality control, reliability of electronics, and health of human being. This paper proposed a humidity sensor based on quartz crystal microbalance (QCM) using graphene oxide as a sensitive layer, and investigated the characteristics of sensor according to the shift of quality factor (Q factor) as well as resonant frequency...
In future nanoscale complementary metal-oxide-semiconductor (CMOS) devices, the high dielectric constant (high-k) gate dielectric film will be shrunk down to a couple of nanometers or down to the sub-nanometer range in the sense of oxide equivalent thickness (EOT). However, as high-k materials, including La 2 O 3 which has been considered to be one of the promising next generation...
