The result is a steady decline in signal quality year after year.", "url": "https://wpnews.pro/news/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner", "canonical_source": "https://www.scmp.com/news/china/science/article/3357541/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner-hair?utm_source=rss_feed", "published_at": "2026-06-18 22:00:08+00:00", "updated_at": "2026-06-18 22:08:49.349316+00:00", "lang": "en", "topics": ["neural-networks", "ai-research", "ai-products"], "entities": ["Zhang Tong"], "alternates": {"html": "https://wpnews.pro/news/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner", "markdown": "https://wpnews.pro/news/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner.md", "text": "https://wpnews.pro/news/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner.txt", "jsonld": "https://wpnews.pro/news/chinese-scientists-create-record-smashing-brain-implant-electrode-array-thinner.jsonld"}}
