摘要
生物组织电特性信息的获取有助于了解组织电生理特性。生物组织是一种由带电粒子构成的导体,在通以交变电流时,这些粒子在正交磁场作用下受到Lorentz力作用而发生机械振动,从而产生声波,声波中包含了生物电特性信息,并可利用声传感器灵敏且无损的检测到。本文利用这种磁声电耦合的方法检测了生物组织的电特性信息。
Information of electric property of bio-tissue helps us investigate the electro-physiology property. Bio-tissue is a kind of conductor composed by particles. Application of perpendicular magnetic fields to oscillating current will cause Lorentz force, which makes particles vibrate. This vibration generates a sound wave which can be detected by an acoustic sensor sensitively and non-invasively. This method is applied to detect electric property of bio-tissue.
