Stimulator ASIC for retinal prosthesis (iBIONICS)

神经刺激可以改善某些神经系统疾病患者的生活。从90年代的几个电极，植入物现在可以处理数百个电极，并为更复杂和更快的刺激策略打开窗口。眼部植入物非常适合这种模式。目前，存在具有200多个电极的植入物。由于电子和材料的改进，这个数字不断增加。然而，这一领域的未来发展面临着新的挑战.电极密度的增加要求在专用集成电路（ASIC）中嵌入越来越多的电子通道，这就要求更大的真实的面积、更大的功耗以及更高的数据速率和更好的效率。iBIONICS已经有了256通道ASIC。Engage plus项目将提出解决方案，将ASIC的当前静态功耗从10 mW降至1 mW以下。该工程将针对供电树以及与为植入物提供能量的光伏电池的相互作用。这些创新的工作将铺平道路，以未来的眼假体的要求。

Neurostimulation can improve life of people with some neurology disorders. From few electrodes in the 90s,implants can now handle hundreds and open windows to more complex and faster stimulation strategies. Theocular implant fits very well in this pattern. Currently, implants with more than 200 electrodes exist. Thisnumber is constantly increasing thank to electronics and materials improvements. However, futuredevelopments in this field are facing new challenges. The electrode density requires to embed more and moreelectronics channel in Application Specific Integrated Circuits (ASIC) which requires more real estate, morepower and a communication link with a higher data rate and a better efficiency. iBIONICS already have a 256channel ASIC. The Engage plus project will consist in proposing solutions for reducing the current static powerconsumption of the ASIC of 10 mW to less than 1 mW. The works will target the power supply tree andinteractions with a photovoltaic cell that will provide energy to the implant. These innovative works will pavethe way to future ocular prosthesis requirements.
