Electric-powered fish, represented by electric cockroaches, generate electricity in the body and can generate electricity with a conversion rate of nearly 100%. A research group at the Japanese Institute of Physical Chemistry developed a new type of generator using the principle of electric power generation organs.
The team applied stimuli to a living body that had been trapped for several days. As a result, the peak current of the pulse current was 19 volts and the peak current was 8 amps in an extremely short time of 10 milliseconds. They also use the pulsed current to successfully start the LED lamp and store it in the capacitor. The stored electricity can make the LED glow for a long time and drive the mini car.
The team also measured the power generation performance of the removed organs. They connected the electrodes to the upper and lower parts of the power generation organ and inserted seven injection needles on the positive side. Each injection needle was also injected with 0.25 ml of acetylcholine solution at a concentration of 1 millimolar. The experimental results showed a peak voltage of 91 millivolts and a peak current of 0.25 milliamperes, and the power generation time was longer than that of the living body coil by more than 1 minute. After the syringe was increased to 20, the peak voltage was increased to 1.5 volts and the peak current was 0.64 mA.
The research team implanted components in the power generating organs to make prototypes for the generators. They cut the power generating organs into a 3 cm rectangular shape and fixed them in a container made of aluminum and silicone. As a result, it was found that the peak voltage was 1.5 volts and the peak current was 0.25 milliamperes when 16 elements were connected in series.
The electrokinase uses an ion pump that is normally present in the cell membrane and uses an adenosine triphosphate (ATP) energy to generate intra- and extracellular ion differences (potential difference). At the same time, neurotransmitter acetylcholine is released at the end of the nerve fibers to stimulate the ion channels in the cell membrane. The sodium ions outside the cell immediately flow into the cell to generate current. The membrane of the power generating organ collects numerous ion pumps and ion channels, increasing the current density. The inline accumulation of cells produces high output power. Due to the difficulty of mass capture, the research team will artificially create power-generating organs in the future, fuse micron and nanofluid technologies, and develop cell structures from the bottom to the top of the molecule to develop the same materials as the power cells.
The research results were published in the recently published "Science Report" magazine in the United Kingdom. (Reporter Chen Chao)
