| 摘要 |
<p>An electrode holder for use with research, medical and agricultural applications, involving the measurement of membrane potentials and of electrochemical impulses in moving, vibrating or contracting tissues is capable of both allowing insertion of needle electrodes or pulled glass electrodes. The design includes a silver rod (2) which is able to move freely within a glass cylinder (6). The glass cylinder (6) is connected to the recording electrode (12), while the silver rod (2) is attached to a suitable amplification system. The glass cylinder (6) is filled with electrolyte so that electrochemical impulses sensed by the electrode (12) can be transmitted to the silver rod (2) and thus to the amplifier and onwards. The overall design enables measurement of stable EMG signals from tissues that are prone to move, vibrate or contract during the period of investigation.</p> |
