HRL researchers originally made headlines with a famous image of a metal microlattice structure resting atop an unaffected dandelion. Now the material has been vetted and confirmed by the Guinness book as having no peer among metals when it comes to weight.

HRL Laboratories, LLC, today announced that researchers in its Sensors and Materials Laboratory have developed an active variable stiffness vibration isolator capable of 100x stiffness changes and millisecond actuation times, independent of the static load.

The Defense Advanced Research Projects Agency (DARPA) has selected HRL Laboratories’ Dr. Logan Sorenson as a “DARPA Riser,” one of approximately 50 early-career researchers who demonstrate the potential to be future technology leaders. During “DARPA Rising,” an event held on September 9, 2015, in St. Louis, Mo., Sorenson will have the opportunity to deliver a poster presentation to the DARPA director and technical team.

According to Dr. Christopher Roper, HRL senior research staff engineer and co-author of “Enabling Ultra-Lightweight Structures: Microsandwich Structures with Microlattice Cores,” published in APL Materials, “Sandwich structures improve the performance of weight-sensitive vehicles like airplanes and helicopters because they’re lighter than solid materials.”

Congratulations to Bill Carter who has been identified as a “2014 key player,” working on materials whose structures can be precisely tailored so they are strong yet flexible and extremely light.
