A proposed general-purpose implantable biomedical system is described. This Internal Human Conditioning System (IHCS) is capable of measuring biomedical data of various kinds on a number of independent input channels. The number and specifications of these channels are software selectable by means of a low-power microprocessor. The system is also equipped with different programmable stimulation devices. These stimulators can deliver a programmable waveform in order to stimulate a specific muscle or to carry out an impedance measurement. The on-board eight bit microprocessor is used for communication with the outside world, by means of a serial link. The processor used is the 68HC11 from Motorola. By extensive use of the processor's 'sleep' mode and by switching off all unnecessary electronics, the amount of power consumed is drastically reduced. At present, a two-channel input chip and a programmable stimulator chip have been developed so that a complete system can be produced. For the sake of illustration, some realized and possible future applications are discussed.
本文描述了一种拟议的通用植入式生物医学系统。这种内部人体调节系统（IHCS）能够在多个独立输入通道上测量各种生物医学数据。这些通道的数量和规格可通过低功耗微处理器进行软件选择。该系统还配备了不同的可编程刺激装置。这些刺激器可以发出可编程波形，以刺激特定肌肉或进行阻抗测量。板载八位微处理器通过串行链路用于与外界通信。所使用的处理器是摩托罗拉的68HC11。通过大量使用处理器的“睡眠”模式并关闭所有不必要的电子设备，功耗大幅降低。目前，已经开发出了一个双通道输入芯片和一个可编程刺激器芯片，从而可以生产出完整的系统。为了说明起见，讨论了一些已实现的和未来可能的应用。
