Currently, in order to stimulate different areas in nervous tissue, brain-machine-interfaces (BMIs) usually rely on multi electrode arrays where each electrode is connected to a wire, that connects to other electronics, all of which has to be safely encapsulated, thus increasing the size of the devices and complicating the surgical procedure for implanted devices. This project aims to develop a silicon multi-junction photodiode that can provide a photovoltage high enough to efficiently excite nervous tissue. A BMI based on this approach could be much smaller and could be powered optically via thin fibres, thus in the long run enabling smaller and safer implants for restoring function in disabled people.

目前，为了刺激神经组织的不同区域，脑机接口（bmi）通常依赖于多电极阵列，其中每个电极连接到一根电线，该电线连接到其他电子设备，所有这些都必须被安全封装，从而增加了设备的尺寸并使植入设备的手术过程复杂化。该项目旨在开发一种硅多结光电二极管，它可以提供足够高的光电压来有效地激发神经组织。基于这种方法的身体质量指数可以小得多，并且可以通过薄纤维提供光学动力，因此从长远来看，可以实现更小、更安全的植入物，用于恢复残疾人的功能。
