Advances in technology allows electronic devices to perform a function similar to a much smaller size.Not long ago, the site Techreview peeling a wireless computer sensor size is just one cubic millimeter. Supermini tool serves as an implant that is placed in the eye of a glaucoma disease.Despite
the very small size, these electronic devices are combining different
types of hardware, including a processor, memory, pressure sensors,
solar cells, thin-film lithium battery, and a transmitter.
Equipment made by scientists from the University of Michigan's useful to read the pressure in the eyes of glaucoma patients for 24 hours, and transmits the data to the patient's treating physician.Pressure by the sensor readings taken every 15 minutes once, and the device will store into memory before the device then upload them to an external device. The solar cell device size is only 0.007 square millimeters constant supply of batteries.The solar cell is exposed to the sun should be about 1.5 hours or at least exposed to outdoor light for 10 hours.According to engineers from the University of Michigan, Dennis Sylvester, the main challenge of the tool is not the size of the circuit is very small, but the size of the power that can be supplied by a battery. All components are designed to use as little power as possible.Therefore, the scientists made this tool with 180 nanometer processing technology, instead of 32 nanometers. Therefore, the smaller the electrical circuit, the more leaks. Meanwhile, the memory cells are also designed to operate at a voltage of 400 millivolts, instead of 1 volt.Pressure sensors only consume an average of 5.3 nanowatt. The processor works at 100 kilohertz (KHz) instead of 1 GHz as in most mobile phones. And its memory has a capacity of 4 kilobits.With its small capacity, the wireless transmitter duty to transmit data wirelessly from memory into a larger storage area that were located 10 cm from the location of the device is implanted.Small sensors like this of course also be made for a variety of biomedical monitoring purposes, such as tracing the development of tumors, overseeing the development of certain pollutants in the environment, or provide surveillance system for security purposes.Sources: teknologi.vivanews.com
