Scientists: the first to develop a urine-powered paper battery

Physicists in Singapore has announced that developed the first laptop battery urine-powered paper to the battery. They said that this credit card-sized battery can be used to power low-cost medical testing tools, and even used as a cell phone in case of emergency power supply.

Urine tests can find diseases, while the new battery will enable the test urine sample can also supply diagnostic equipment. Singapore Institute of Bioengineering and Nanotechnology of the Ki Bang Lee, said: "We are working to develop low-cost testing for the disease, the credit card-sized disposable biochip. Our battery can be easily integrated into such devices, in the urine and the like fluid or blood and other biological fluids to provide current contact. "

During the current bio-chip IBM 92P1102 Battery diagnostic tests, the need for external sensors (eg laser scanner) or an external power supply (such as conventional batteries). The Lee's sensor and battery technology will be installed in a plastic chip. Battery by a layer of soaked filter paper in copper chloride composition of this layer of filter paper clip in between the magnesium and copper strips. The urine of salt caused a chemical reaction, magnesium metal layer as the anode to lose e-, copper and copper chloride as the cathode to release electrons. Lee said that the urine-powered battery only 0.2 milliliters of urine can provide about 1.5 volts, the power of 1.5 milliwatts of electricity. If you activate the battery for the first time to run 15 hours later by adding a second drop of urine, the urine can be issued to add more IBM 08K8196 Battery power. The battery is currently available in a one-time equipment, you also can not be used as a laptop or iPod power supply.

Now the battery in the factory before they had been activated (if you are buying a hoarding goods, time, hoarding, and require re-activation). So, no need to bought off enough to come back in the first three minor more than 12 hours

Battery calibration method:

When the battery capacity DELL 08K8194 Battery dropped a lot of sense to use significantly less time and can be used when the battery calibration, the official statement is the best 3 months corrected time.

1. Press F2 to enter BIOS

2. Chose to enter the menu POWER

3. Select START BATTERY CALIBRATION later, you are prompted, then connect the power adapter in order to facilitate machine-to-charge the battery.

4. When the screen appears, the following prompt, please remove the power adapter. And wait for the machine automatically shut down to complete discharge.

PLEASE REMOVE AC ADAPTER

5. To be connected to the adapter is turned off, the charge to the charging indicator light is off, that is the completion of the battery IBM 92P1087 Batterycalibration
