植入式生理信号无线遥测系统用于长时间测量清醒无束缚的大鼠、小鼠、兔子、比格犬、猴子、鱼等多种动物的心率、体温和活动量等生理参数。使用此系统可以保证动物在笼内自由活动，不需要麻醉或束缚，这样测量到的生理信号更能反映自然状态下的动物生理状况。可用于生物节律研究和相关的生命体征监测。

植入式生理信号无线遥测系统可无线遥测和记录实验动物的：心率、体温、活动量.

植入式生理信号无线遥测系统由植入体(E-Mitter)、接收数据转换器(Receiver)、电缆和记录分析计算机(VitalView)构成。1厘米大小的植入体E-Mitter集成了传感器、放大器和无线信号发射器，根据测量信号不同有多种规格。植入式E-Mitter转发器不需电池，由接收数据转换器(Receiver)输出电力。实验人员将植入体埋入动物皮下，生理信号被植入体采集到并转换成相应的电信号后用无线电发射出来，由饲养笼下方的接收器接收到并传递给数据转换器，完成数据转换后送入ZY处理器进行数据处理。系统最多可同时连接32个接收器，完成大规模的试验。

植入体(E-Mitter)是植入在动物体内的微型设备,它集成了传感器，放大器，数字转换，无线发射的功能并解决了生物体的抗排异反应。植入体有用于测量生物心率，体温和活动量等多种参数的规格。

植入式生理信号无线遥测系统的主要特点：

Ø 无线遥测

Ø 植入式E-Mitter转发器没有电池

Ø 长期监测-植入装置后允许连续、遥测实验动物一生

Ø 准确、可靠，报告清醒无束缚动物的生理和行为数据

E-Mitter（植入体系统）主要技术参数:

ER4000 信号接收器
ER4000信号接收器，用于给E-Mitters充电和接收E-Mitters传回来的测量数据。适合标准的大小鼠饲养笼具。

信号接收器的主要参数

激发接收器和感应器通过VitalView软件连接到电脑。最多可以记录240个数据通道，典型应用120个测试对象，对于E-mitter系统最多32个测试对象。

VitalView软件可以设置实验参数和采集数据。软件管理与硬件的连接，并且储存显示基本的图形化的数据分析。软件也提供统计形式的数据显示，可以输出数据。

Telemetry - used to monitor temperature, gross motor activity and heart rate data.
Physiological and behavioral monitoring oftransgenic mice and other laboratory animals has never been simpler. Through the use of biotelemetry and a variety of available sensors, it is possible for VitalView to monitor up to seven different physiological or behavioral parameters from a single laboratory subject

Combinations of the following parameters may be monitored for multiple laboratory subjects using VitalView:
Body Core Temperature
Heart Rate
Gross Motor Activity
Running Wheel Turns
Drinking/Licking Frequency
Feeding Behavior
Ambient Temperature
Ambient Light

E-Mitter Battery-Free Implantable Transponders：
Using telemetry to provide temperature, gross motor activity and heart rate data. An E-Mitter is a small implantable transponder that is powered by capturing energy from electrical fields generated by the ER-4000 Energizer/Receiver. This allows the E-Mitter to operate without batteries and remain implanted indefinitely to monitor the subject''s temperature, activity or heart rate. As a result, high costs and downtime of explantation, refurbishment and reimplantation are avoided.
