In the context of environmental pollution and energy resources in the growing tension, solar energy as a new type of green and renewable energy has been paid for more and more attention. The most attention focuses on photovoltaic. But the stability of PV (photovoltaic) system output is poor, the grid will seriously affect the power quality. To ensure the normal operation of photovoltaic power generation...
An ultrasonic telemetry and a neural stimulator are presented. The wireless charging, data transmission and neural stimulation are demonstrated in this work. A frequency-shift keying with pulse-width modulation is adopted for wireless charging and data transmission. The stimulator provides an output current of 0μA~900μA. The frequency of the current pulse is from 60Hz to 320Hz. This ultrasonic telemetry...
An ultrasonic power/data telemetry and a neural stimulator are presented. An on–off keying with pulse modulation is adopted for ultrasonic signal transmission. The ultrasonic power is used to charge a battery. The ultrasonic data are used for neural stimulation, and an animal study is also demonstrated. The range of the stimulation current is 0–640 . The frequency of the stimulation current...
