At present, there are many problems in infrared technology of the near-field smart meter reading, such as being easily interfered by light, low transmission rate, long meter reading time, short operating distance and so on. To above issues, this paper presents a technical scheme of field meter reading based on Bluetooth technology and broadband carrier instead of infrared technology, and designs an...
In this paper, we report on the fabrication of biomimetic silicon tip arrays using metal catalytic wet etching silicon followed by a short time reactive ion etching (RIE) process. Silicon post arrays with different space and length can be prepared by 2D colloidal crystal assisted metal catalytic wet etching. After that, silicon tip arrays with different space and length can be prepared using RIE on...
