Imagine a medical device so tiny it fits through a needle—yet can monitor your brain signals *wirelessly*. A team from China and Singapore just made this sci-fi concept a reality!
The Future of Brain Monitoring
Researchers at Huazhong University of Science and Technology (HUST) and Nanyang Technological University developed a 2mm hydrogel cube sensor that’s injected into the skull using a simple needle. No invasive surgery required!
How It Works
Once implanted, the hydrogel shifts shape in response to changes in pressure, temperature, pH, or fluid flow. These changes alter ultrasound waves detected by an external probe—like a high-tech game of Marco Polo for your brain.
Biodegradable & Safe
The sensor dissolves naturally in 18 weeks without triggering immune responses (tested in rats). Pigs trials showed accuracy matching bulkier wired devices—a win for animal *and* human healthcare!
Beyond the Brain?
Lead researcher Zang Jianfeng says the tech could monitor other organs too. Think of it as a Fitbit® for your insides! Published in Nature, this innovation could redefine neurology and chronic disease care.
