SUMMARYWe developed an inductively powered integrated electronic prosthesis, allowing for the trade-offs among implant functionality, circuit complexity, power consumption, hardware cost, and integrity of data recovery, for a multichannel microstimulation circuitry. The proposed prosthesis features energy efficiency and is capable of up to 40 scan/s with 240 stimulus channels in mode I and three times resolution at the same scan rate in mode II under a carrier frequency of 2MHz. In order to satisfy future upgrade demands, the prototype has been constructed with a 16-channel-based stimulation scheme so that the spatial resolution of the design can be extended toward various experimental purposes. The circuit techniques used in the system are detailed. Results from fabricated chips using a 0.18-mm CMOS process are given as proof of concept.

In view of the vigorous development of simulation training technology, the classification, research status and development direction of simulation training technology at home and abroad are studied, which provides reference basis for equipment simulator research. Modern simulation trainer is a multi-component platform by means of simulation technology, which has the characteristics of more pertinence and more comprehensive training elements than traditional training mode.
