nano sensors to detect heart attack
A team of Indian scientists and engineers has developed affordable sensors using nano materials to detect a heart attack quickly.The device also has the capability to transmit the data to the doctors or concerned persons who are far apart from the tagk of detecting the heart attack. Any unusual movement o0r vibratio0n in the heart wi0ll be detected by the device using the The three-dimension sensors use nano electrical mechanical system (NEMS) of its polymer . The device produces an electrical signal for detecting a cardiac symptom. a cantilever has been built in the sensor for the detection of stress or myocardial infarction. And these signals are converted to electrical signals.
The electrical power required for the operation of the device is generated from the biochemical activity of the enzymes in the heart. The operatin of the device is based on the fact that When the heart goes through severe stress or strain, it suddenly releases enzymes (protein molecules) in excess, causing pressure on its blood vessels and exertion, which manifest as chest pain, perspiration or even a cardiac arrest. The nanotechnology device will enable cardiac diagnosis affordable and aslo the diagnosisis quick anda lot of livs can be saved.
