Excited to share our recent collaborative work on fatigue-resistant hydrogel fibers. They can deliver light in complex in vivo environments for optogenetics-assisted pain inhibition⁦⁦Xinyue Liu⁩ ⁦⁦Bioelectronics @ MIT⁩ ⁦⁦Xuanhe Zhao⁩ nature.com/articles/s4159…

The Siyuan Rao lab developed flexible and fatigue-resistant optical fibers made from hydrogel that allow optogenetic manipulations in the periphery in freely behaving mice. Xinyue Liu Bioelectronics @ MIT Xuanhe Zhao nature.com/articles/s4159…

* Soft fatigue-resistant hydrogel optical fibers that reliably function in living animals for months. * Fatigue-resistant reliable connections with other devices. * Easy and reproducible protocol. * The paper can be downloaded here. rdcu.be/doZ5f

Can vibrational ‘fingerprints’ lead to high-throughput characterization of metamaterials? In our work, out in nature today, we present a non-contact framework to rapidly characterize microscale metamaterials in the dynamic regime! 🔗: nature.com/articles/s4158… MIT MechE Massachusetts Institute of Technology (MIT)

Using laser pump/probe schemes, we extract the full (dynamic) effective elastic tensor of metamaterials, allowing a fully experimental representation of elastic surfaces as well as quantifying dynamic stiffening.

Through wave propagation in the MHz regime, we construct partial dispersion relations that enable characterization of acoustic metamaterials, also identifying anisotropic attenuation of these waves.

Leveraging the richness of responses, we demonstrate this framework as a route to quantify ‘invisible’ defects in microscopic components/materials. Two common defect types at these scales result in quantifiable defect densities in each.

Last but not least, huge congrats to team members Yun Kai 凯韵 , Somayajulu Dhulipala, Rachel Sun, and J. Lem for turning this framework into reality, along with collaborators T.Pezeril and W.DeLima. Exciting path ahead in dynamics & ultrasound w/ metamaterials!
