The acquisition of surface bio-electricity in some special occasions, such as detection of physiological parameters under the state of rapid motion, monitor for astronauts 'health indicators in flight training, must get rid of wires constraints and turn to wireless send and receive mode. 但在一些特殊场合(如快速运动状态下生理参数检测、宇航员飞行训练中健康指标监测)的体表生物电采集与传输必须摆脱电线束缚,改用无线发送与收取方式。
