摘要(Abstract):

本文报道采用国产元件研制、适用于玻璃微电极的微型遥测发射机。整个装置由射极跟随器、脉冲放大电路、振荡电路和发射天线组成。采用普通半导体收音机即可接收与解调。本装置具有高输入阻抗、微功耗和低重量等特点。已成功地用于行为脑机制的研究。
A miniature telemetry device for transmitting the unit activity in awake animal was presented.The amplifier,the oscillator circuit and the antenna.The impulses could be accepted and demodulated by popular transister radio.The main parameters of this device:the telemetry frequency is 6.5MHz;the radius of telemetry is 2m;the input signal is 100 v-2000 v;the input impedance is over 1000m when the frequency is 200Hz,and is about 200m when is 1000Hz; the size of external form is 26mm×26mm×46mm;the weight is 40g;Power source is qv.The character of device is as follows:high input resistance, minitype,miniature power and weightless.It had used in brain and behaviour researches successively.
