According to foreign media reports, recently, scientists' latest research shows that a micro nano generator can be implanted into the body to obtain energy from heart beating, provide power to sensors implanted in animals, and provide early warning for various diseases such as hypoglycemia
a micro nano generator can be implanted into the body to obtain energy from the beating of the heart and provide electrical energy to the sensors implanted in the animals.
at present, scientists have successfully implanted the nano generator into experimental mice and obtained current from the beating of the mouse's heart. The research team led by wangzhonglin of the California Institute of technology believes that the current generated by the nano generator can drive the in vivo sensor
wangzhonglin pointed out that the zinc oxide wires established at the nano level can be used as piezoelectric materials, which can convert mechanical energy into electrical energy. Therefore, he and his colleagues have built a flexible micro China to issue a "plastic ban" type generator, which can convert the breathing or heart beating of living animals into electrical energy
the research team placed the zinc oxide wires in a flexible polymer medium, making the nanowires incorporated in different forms. They encapsulated the device in a polymer to shield the liquid in the body, so as to ensure that any current generated by the device is not disturbed by the background
the researchers attached the 5mm long and 2mm wide rectangular device to the diaphragm muscle of mice with tissue 3 and zigzag fixture adhesive;, "This nano generator is so small that you can hardly see it with the naked eye," Wang said. With each breath, the nanowires will deform to produce 4 picoamps of current at 2 MV extra potential
after that, researchers implanted similar nano devices into the hearts of different experimental mice, which can generate 30 picoamps current under 3 MV extra potential voltage. Although the generated power is very small, the researchers hope that it can be output in proportion, which will be enough to provide power for a single implanted nano sensor, such as a blood pressure sensor or a glucose sensor. These sensors have a moderate demand for current and do not require a continuous current supply
according to Wang Zhonglin, such nano devices can capture mechanical energy in vivo in any direction, so they do not have to be arranged in a specific array. He stressed that any mechanical energy of living animals can be converted into electricity to provide power for nano sensors. In the future, we expect them to enter the human clinical experiment stage and become the real micro generator in the human body
