日本拓殖大学工程学系的小林健二副教授研制成功了诊断脑动脉瘤的传感器。把这种直径4.4厘米、重95克的铜质传感器置于患者跟睑上,便可测知是否存在脑动脉瘤。血管瘤形成后,则该部位的血流不规则,出现杂音。小林副教授试图通过与脑相连的眼球来检测脑动脉瘤。该传感器利用压电性高分子膜把声的振动转换成电信号,能敏感地接收波长为100～2300赫兹的声波。 Professor Takashi Kobayashi of Japan’s Takushoku University Engineering Department successfully developed a sensor for diagnosing cerebral aneurysms. The 4.4 centimeters in diameter, weighing 95 grams of copper sensor placed on the patient’s eyelid, can detect the presence of cerebral aneurysm. After the formation of hemangiomas, then the site of irregular blood flow, the emergence of noise. Associate Professor Kobayashi attempts to detect brain aneurysms through the eye connected to the brain. The sensor uses piezoelectric polymer film to vibrate the sound into electrical signals, sensitive to receive the wavelength of 100 ~ 2300 Hz sound waves.
