Industry trends

1. Introduction of nanometer generator:

       Nanogenerators are based on regular zinc oxide nanowires, which convert mechanical energy into electrical energy in the nanometer range, and are the smallest generators in the world.

        At present, nanogenerators can be divided into three categories: piezoelectric nanogenerators, triboelectric nanogenerators, and pyroelectric nanogenerators. Application fields: medicine, military, wireless communication, wireless sensing.

2. Difficulties in testing: 

       Due to the technical characteristics of nano power generation itself, it is necessary to test the electrical energy generated by the mechanical energy per unit area, the generated voltage, the tiny current and the power signal during the research process. The voltage is basically several volts or even tens of volts, and the current is generally uA or even nA level, power in mW or even uW level. How to accurately test small current and power signals is difficult, and the requirements for the accuracy and stability of the test equipment are very high.

        S-type source measure unit is the first choice in the industry in the field of small electrical signal testing.

3. Nano power generation test plan:

       Small current signal test:

        1. Using insulating material nano power generation technology, the general source internal resistance is at GΩ level, and the test current is at pA level, so the industry uses electrometer 6514+Stanford SR570 (low noise current preamplifier)+special acquisition software to generate power Current data collection.

        2. For general-purpose nano-power generation technology, the general source internal resistance is tens to hundreds of MΩ, and the current is generally at nA, uA level. It is recommended to use digital source measure unit + S-type software to test.
