构建先进的智能医疗设备 (SMD) 需要创新的电路和系统技术。高可靠性和极低功耗是此类植入式无线控制微系统必须优先考虑的主要标准。典型的设备由多个集成模块组成，这些模块组装在薄基板上，提供了体内放置的灵活性。为了提高安全性并在植入后进行故障排除，需要监测电极-组织界面状况。为了提高可控性和可观测性，完全集成的二进制相移键控 (BPSK) 解调与无源调制方法相结合，允许外部控制器和植入物之间进行全双工数据高数据速率通信。报告了恢复膀胱功能的周围神经接口、皮质多通道刺激器以及皮质监测设备等案例研究。
Innovative circuits and systems techniques are required to build advanced smart medical devices (SMD). The high reliability and very low power consumption are among the main criteria that must be given priority to implement in such implantable and wirelessly controlled microsystems. A typical device is composed of several integrated modules to be assembled on a thin substrate providing placement flexibility in the body. Monitoring of electrode-tissue interface condition is needed for enhanced safety, and for enabling troubleshooting after implantation. In order to improve controllability and observability, fully integrated binary phase-shift-keying (BPSK) demodulation combined with a passive modulation method allows full-duplex data high data rate communication between external controllers and implants. Case studies such as peripheral nerve interfaces to recuperate bladder functions, cortical multichannel stimulator, as well as cortical monitoring devices are reported.
