微型新型腦部植入物可無線監測活動
Tiny new brain implant monitors activity wirelessly
科學家們研發出微型光電無線電極（MOTE），實現了醫學上的一大里程碑。
Scientists have achieved a medical milestone with the development of the Microscale Optoelectronic Tetherless Electrode, or MOTE.
這個微小的裝置大約如鹽粒般大小，正在革命性地改變我們研究大腦的方式。
About the size of a grain of salt, this tiny device is revolutionizing how we study the brain.
與需要笨重電線和電池的傳統大腦植入物不同，MOTE 完全無線。
Unlike traditional brain implants that require bulky wires and batteries, the MOTE is completely wireless.
它由穿過頭皮和顱骨的外部紅外線雷射供電，將光能轉換為電能。
It is powered by external infrared lasers that pass through the scalp and skull, converting light into electricity.
為了傳輸資訊，它使用了一種稱為脈衝位置調變的複雜通訊方法。
To send information out, it uses a sophisticated communication method called pulse position modulation.
這項創新由康乃爾大學與南洋理工大學的研究人員共同領導，克服了神經科學中的一大難題：在不引發感染或機械創傷的情況下，長期監測神經活動。
Co-led by researchers at Cornell and Nanyang Technological University, this innovation overcomes a major hurdle in neuroscience: monitoring neural activity long-term without infection or mechanical trauma.
儘管目前尚未準備好用於人體，但這項微小的技術已為未來監測大腦、脊髓或心臟打開了大門，有潛力變革臨床診斷。
While not yet ready for humans, this tiny tech opens doors for future monitoring of the brain, spinal cord, or heart, potentially transforming clinical diagnostics.
