| Zhong-Lin Wang pointed out that the level established in the nano-zinc oxide wires can be used as piezoelectric material, the material to the mechanical energy into electrical energy. Therefore, he and his colleagues built a flexible micro-generator can be animals living breathing or heart beat and other natural body of behavioral change into electricity.
team will be placed in a zinc oxide wires flexible polymer medium, making the nanowires in different forms into one. They package the device in a liquid polymer shielding the body, thus ensuring that the device are not subject to any current generated by the background interference. researchers used tissue adhesive to the length of 5 mm wide and 2 mm rectangular device attached to the mouse diaphragm muscle, Zhong-Lin Wang said: \can see. \ ,football uniforms, the researchers implanted the heart of laboratory mice of different nano-like device, can produce voltage of 3 mV 30 pico amps potential (picoamps) current. Although the power generated is very small, the researchers hope to proportional output, which will be sufficient to provide a single power implantable nanosensors, such as: blood pressure sensor or glucose sensor. The sensors for the current needs of moderate and does not require constant current supply. Zhong-Lin Wang said that this nano-device can capture in any direction in vivo mechanical energy, so they do not have a specific arrangement of the array. He stressed that the living animals of any mechanical energy can be converted into current, provide power for the nano-sensors. The future, we expect them to enter human clinical trials stage, as the human body truly \ Recently, scientists, new research shows a tiny \status of early warning. a tiny \experimental mice and rats beating heart from the get current. Responsible for the study is the California Institute of Technology research team led by Zhong-Lin Wang, they think the current nano-generators can be driven in vivo sensors. |
