Adhesive, non-fibrotic neural interfaces enable long-term, drug-free blood-pressure reduction

Humans, machines, and AI are steadily converging. In human–machine integration, a widely accepted principle is to make devices soft to enable long-term integration—for example, in implantable bioelectronics. The MIT Zhao Lab (https://t.co/lUa4iWsn1X) proposed an additional principle: make devices adhesive so they form long-term, non-fibrotic, stable, and high-efficacy interfaces for seamless human–machine integration.

In our latest work, we report that:
* Adhesive, non-fibrotic neural interfaces can be applied to multiple peripheral nerves.
* Electrical stimulation via these adhesive interfaces achieves long-term, drug-free lowering of blood pressure.
* We provide a simple, general, and practical method for fabricating the adhesive electrodes.

Inspired by nature — and for nature 🌍: our @PNAS paper shows how seashell-inspired designs can make recycled plastics more reliable and potentially cut manufacturing costs of packaging materials by nearly 50%, while keeping plastics out of landfills.

In the paper, you’ll find our uncertainty-aware tension-shear-chain model, a beautiful experimental demonstration, and a @McKinsey-style case study for stretch wraps.

Can a soft robot swim backwards? As part of our effort to design ingestible robots, we use 3D printing to investigate the propulsion behavior of elastic artificial flagella. Our results, recently published in a Soft Matter Emerging Investigator article, demonstrate that a flagellum’s curvature dictates both the magnitude and direction of propulsion. These findings highlight the possibility of bidirectional swimming through on-demand curvature modulation during active oscillation, thereby enhancing the dexterity of flagella-driven soft robots for a wide range of microscale applications.

Spider silk is nature’s composite: steel-strong yet elastic. But its gigantic, repetitive proteins have kept full-strength synthetic fibers out of reach. Enter our SilkomeGPT-driven multi-agent framework that combines language models with physics reasoning, in research led by my graduate student @IrisWeiLu. We trained a language model on ~1,000 real spidroins, generated thousands of novel sequences to explore diverse mechanical features, folded them virtually, then yanked each atom-by-atom in steered molecular dynamics. We generated thousands of force curves that pinpoint which glycine coils give stretch and which β-sheet blocks lock in strength. Along the way, we uncovered a hidden rule: toughness tracks with adaptability. The number of secondary structure transitions - shifts between helix, sheet, and coil during pulling - is highly predictive of molecular toughness (R = 0.77). Proteins that reshape themselves under strain absorb more energy. We also found that protein length alone predicts toughness with R = 0.93, offering a simple lever for energy absorption. But at the fiber scale, mechanics diverge - revealing that hierarchical assembly, not sequence alone, governs real-world strength. We now have a quantitative map from sequence to mechanics, a GPS for designing tougher, more resilient and greener fibers. Applications include custom biomedical materials, parachute lines, biodegradable sutures, even soft exoskeleton cables or soft robotics actuators - all tuned in silico before a single bioreactor run.

🌍♻️🚀 Lessons from Earth. Blueprints for Mars.

My @TEDxAtlanta talk explores how the same resourcefulness that helps us reuse and recycle plastic waste on Earth could help us construct life-supporting habitats on Mars.

It’s a story about turning scarcity into strength - using #mechanics, #materials engineering, #biology, and a bit of #AI to build smarter, lighter, and longer-lasting structures.
