Abstract

The invention provides a friction electronics tuning diode and a modulator circuit applying the friction electronics tuning diode. The friction electronics tuning diode comprises a friction nanometer electric generator, an impedance element and a PN junction element; the first end of the PN junction element is connected to the first output end of the friction nanometer electric generator, and the second end of the PN junction element is connected to the second output end of the friction nanometer electric generator through the impedance element, wherein the first end of the PN junction element is further connected to the first output end of the friction electronics tuning diode, the second end of the PN junction element is connected to the second output end of the friction electronics tuning diode, and the junction capacitance of the PN junction element is regulated and controlled by an adjustable electrostatic potential generated by the friction nanometer electric generator under the effect of external force. Active modulation of the friction nanometer electric generator for PN junction equivalent capacitance is realized, and active human-machine interaction modulation for analog signals is realized, so that the preparation technology is simple, the material selection is wide, and the cost is relatively low.

Description

technical field [0001] The invention relates to the field of flexible electronics, in particular to a triboelectronics tuning diode and a modulation circuit using the same. Background technique [0002] With the development of society, people's demand for electronic devices in the fields of instant messaging, smart wearable devices, personal health monitoring and wireless sensing is increasing and the requirements are getting higher and higher. However, most of the current electronic devices lack an effective direct interaction mechanism with the external environment, and it is difficult for people to actively participate in the regulation of electronic circuits. In the field of electronic circuit control, analog signal modulation plays a very important role. How to realize the active human-computer interaction modulation of analog signals has become a huge challenge for researchers.
