Televox is not a dream, to the soft sensor technology from Sohu cad2012序列号和密钥

Televox is not a dream, to the soft sensor technology from Sohu [Technews] of current medical science news even so developed, but can detect sound through the skin vibration equipment, mainly the stethoscope just after all is said and done. But the materials scientists at the University of Illinois at Urbana Champaign, Bana, recently released a soft audio sensor, people can put it on the skin can even monitor the heartbeat, speech recognition. It is expected to be used in the diagnosis of the disease, but also allows people to use voice control robot. The device uses a small, low power commercial MEMS accelerometer, coated in a viscous and elastic silicone rubber. The research team said that these accelerometers are adjusted in the range of 0.5~550 Hz, which is the frequency of the vibration of the body’s vital organs. Retractable wire can be connected with the accelerometer amplifier, resistor and capacitor, similar in appearance to a OK stretch, only 20 mm thick, weighs 213.6 mg. Its soft and flexible properties allow people to wear parts of the body bent, such as the neck; and silicone rubber also has a good permeability, help sweat evaporation. In the experiment, the device can continue while receiving several different audio data, such as heart valve opening and closing the blood through carotid artery pulsation, vibration of the vocal cords, even in the gastrointestinal peristalsis. The research team tested the older volunteers in Arizona’s private medical center, found that this device can measure the heart murmur; in the heart pump experiment, evidence of sensor can detect a potentially fatal blood clot. They also through the sensor in the throat, can be found as a voice interface, the instructions are sent to the computer, to control the robot or playing electric. For example, let the subjects said that the mouth, down, left and right to manipulate the elf game, while the sensor to determine the accuracy of instructions up to 90%. In addition, acoustic sensors can also help people with speech problems. The future application of the situation may also contain the soldiers on the battlefield, or in the disaster scene in return, when they are busy with other hands, you can through the sensor to convey instructions to the robot assist operation. The sensor includes an electrode that is able to record electronic signals from the body and monitor the status of the heartbeat and cardiac pacemaker. At present, although the need to rely on the transmission of information, but in order to achieve a more practical effect, the research team said that it would further improve the wireless transmission mode, and enhance the range of induction frequency of the device reaches 2000 Hz, which can voice all vibration detection range, and a radio microphone.
