Disclosed is a method for protecting data information of an electronic device, comprising the following steps: 1) performing power-on detection on an electronic device of which production and installation are completed, detecting the stray capacitance of a signal line thereof, and recording same as a standard value of the signal line; 2) during a power-on operation, monitoring the stray capacitance of the signal line; 3) comparing the monitored capacitance value with the standard value, and entering step 4) when exceeding the set threshold value, otherwise entering step 2); and 4) erasing significant data in the electronic device. The method uses the manner of monitoring the stray capacitance to monitor the contact of outside foreign matter with the signal line, guarantees the security of data in the electronic device, and has the characteristics that the implementation process is simple and easy, safe and reliable, and the cost is low.

An enhanced receiver for wireless power transmission is disclosed. The receiver may be able to convert RF waves into continuous, stable and suitable voltage or power that can be used for charging or powering an electronic device. The receiver may include an antenna array for extracting and rectifying power from RF waves or pockets of energy. An input boost converter in the receiver may step up and stabilize the rectified voltage, while charging a storage element in the receiver.
