随着集成电路和固体电路技术的发展,遥测、刺激、生理控制用的一些复杂仪器,设计植入使用时,涉及到体积和重量的要求。但是,有两个困难因素使其进展大为减慢,一是对换能器的生物相容性和体积的要求,二是要求包装材料和包封技术能保护仪器在规定寿命内不受人体环境的影响。为了使微功率电路的功能正常,电子仪器应当装在密封的环境里。但是,这种包封和外壳不能使总体积和总重量超过很多,也不应限制电子仪器的性能。
With the development of integrated circuit and solid-state circuit technology, telemetry, stimulation, and physiological control of some complex instruments, design and implantation, the volume and weight requirements involved. However, there are two difficult factors that have greatly slowed down their progress. The first is the biocompatibility and volume requirements of the transducer. The second is the requirement that the packaging material and encapsulation technology protect the instrument from the body Environmental impact. In order to make the function of the micro-power circuit normal, the electronic equipment should be installed in a sealed environment. However, such enclosures and enclosures do not result in a significant excess of total volume and weight, nor should they limit the performance of electronic equipment.
