Capacitive micro-electromechanical system (MEMS) accelerometer and manufacturing method thereof

The invention provides a capacitive micro-electromechanical system (MEMS) accelerometer, which comprises a first silicon cover plate layer, a middle silicon layer and a second silicon cover plate layer which are arranged in sequence, wherein the middle silicon layer comprises a first silicon island and a second silicon island; the silicon islands are formed inside a silicon framework and separated from the silicon framework at intervals; the first silicon island is contacted with a metal electrode of the first silicon cover plate layer; the second silicon island is contacted with a metal electrode of the second silicon cover plate layer; the first silicon cover plate layer further comprises a first metal electrode through hole, a second metal electrode through hole and a silicon electrode through hole which are formed in a first silicon substrate; the first metal electrode through hole corresponds to the position of the first silicon island; the second metal electrode through hole corresponds to the position of the second silicon island; the silicon electrode through hole corresponds to the position of the silicon framework; and an insulating layer is arranged on the inner wall of each through hole, and each through hole is filled with metal electrically conductive material. By adopting the capacitive MEMS accelerometer, all electrodes of the accelerometer can be led out on the same silicon surface, so that wafer level bonding of the accelerometer is realized and the accelerometer can be packaged by adopting the flip chip technology.

Mobile authentication method, mobile authentication device and mobile authentication system

InactiveCN104796258ASolve instability and security risksAvoid potential lossUser identity/authority verificationInstabilityWearable Electronic Device
The invention aims to provide a mobile authentication method, a mobile authentication device and a mobile authentication system. The mobile authentication method includes establishing matching relations between mobile device sides and wearable electronic device sides; transmitting to-be-authenticated information to wearable electronic devices when the to-be-authenticated information is acquired by the mobile device and connection conditions of the mobile device and the wearable electronic devices meet authentication conditions; enabling the wearable electronic devices to authenticate the to-be-authenticated information; transmitting authenticated information to the mobile device. Compared with the prior art, the mobile authentication method, the mobile authentication device and the mobile authentication system have the advantages that problems of instability and potential safety hazards due to loss of existing mobile devices can be solved by the aid of the wearable electronic devices which are difficult to lose; potential loss due to possible loss of the mobile device can be prevented, the problem of illegal use can be solved, and the mobile authentication usability and safety can be improved.
