Most current wireless biomedical signal transceivers use range-limiting communication. This work presents a low-cost biomedical signal transceiver that uses Bluetooth wireless technology. The design is implemented in a modular form to be adaptable to different types of biomedical signals. The signal front end obtains and processes incoming signals, which are then transmitted via a microcontroller and wireless module. Near real-time receive software in LabVIEW was developed to demonstrate the system capability. The completed transmitter prototype successfully transmits ECG signals, and is able to simultaneously send multiple signals. The sampling rate of the transmitter is fast enough to send up to thirteen ECG signals simultaneously, with an error rate below 0.1% for transmission exceeding 65 meters. A low-cost wireless biomedical transceiver has many applications, such as real-time monitoring of patients with a known condition in non-clinical settings.
当前大多数无线生物医学信号收发器采用有限距离通信。这项工作展示了一种使用蓝牙无线技术的低成本生物医学信号收发器。该设计以模块化形式实现，以适应不同类型的生物医学信号。信号前端获取并处理输入信号，然后通过微控制器和无线模块进行传输。开发了LabVIEW中的近实时接收软件来演示系统功能。完整的发射器原型成功传输了心电图信号，并且能够同时发送多个信号。发射器的采样率足够快，能够同时发送多达13个心电图信号，在超过65米的传输中错误率低于0.1%。低成本无线生物医学收发器有许多应用，例如在非临床环境中对已知病情患者进行实时监测。
