RESEARCH TRIANGLE PARK, N.C. — Army-funded researchers discovered how to make materials capable of self-propulsion, allowing materials to move without motors or hands.
Researchers at the University of Massachusetts Amherst discovered how to make materials that snap and reset themselves, only relying upon energy flow from their environment. This research, published in Nature Materials and funded by the U.S. Army, could enable future military robots to move from their own energy.
“This work is part of a larger multi-disciplinary effort that seeks to understand biological and engineered impulsive systems that will lay the foundations for scalable methods for generating forces for mechanical action and energy storing structures and materials,” said Dr. Ralph Anthenien, branch chief, Army Research Office, an element of the U.S. Army Combat Capabilities Development Command, now known as DEVCOM, Army Research Laboratory. “The work will have myriad possible future applications in actuation and motive systems for the Army and DOD.”
Researchers uncovered the physics during a mundane experiment that involved watching a gel strip dry. The researchers observed that when the long, elastic gel strip lost internal liquid due to evaporation, the strip moved. Most movements were slow, but every so often, they sped up.
These faster movements were snap instabilities that continued to occur as the liquid evaporated further. Additional studies revealed that the shape of the material mattered, and that the strips could reset themselves to continue their movements.
“Many plants and animals, especially small ones, use special parts that act like springs and latches to help them move really fast, much faster than animals with muscles alone,” said Dr. Al Crosby, a professor of polymer science and engineering in the College of Natural Sciences, UMass Amherst. “Plants like the Venus flytraps are good examples of this kind of movement, as are grasshoppers and trap-jaw ants in the animal world.”
Snap instabilities are one way that nature combines a spring and a latch and are increasingly used to create fast movements in small robots and other devices as well as toys like rubber poppers.
“However, most of these snapping devices need a motor or a human hand to keep moving,” Crosby said. “With this discovery, there could be various applications that won’t require batteries or motors to fuel movement.”
After learning the essential physics from the drying strips, the team experimented with different shapes to find the ones most likely to react in expected ways, and that would move repeatedly without any motors or hands resetting them. The team even showed that the reshaped strips could do work, such as climb a set of stairs on their own.
“These lessons demonstrate how materials can generate powerful movement by harnessing interactions with their environment, such as through evaporation, and they are important for designing new robots, especially at small sizes where it’s difficult to have motors, batteries, or other energy sources,” Crosby said.
The research team is coordinating with DEVCOM Army Research Laboratory to transfer and transition this knowledge into future Army systems.

ANOKA, Minnesota – February 3, 2021 – Federal Ammunition is committed to empowering our nation’s injured veterans. Since 2011, Federal Ammunition has supported Wounded Warrior Project (WWP) and the nonprofit’s free programs and services with an annual contribution to the Minnesota Wounded Warrior Charity Golf event. To date, the total contribution is just shy of $248,000 dollars.
Wounded veterans face significant challenges when they return to civilian life, and through the generous support of donors and corporate partners, WWP provides support during their recoveries, wherever they are in that journey.
“I’m proud of this program,” said Rick Stoeckel, Federal Ammunition’s Shotshell Product Director. “When our wounded heroes return, the needs are great and Federal is proud to assist in any way that we can, and the consumers have responded by purchasing the product that supports Wounded Warrior Project in our backyard of Minnesota and throughout the United States.”
Through our financial contribution, Federal Ammunition is directly supporting the programs and services that give warriors access to independence, mental and physical health, career counseling, peer support and connections to other veterans, and family support—free of charge.
Even the most challenging targets are no match for consistent, hard-hitting Federal Top Gun target loads. High-quality lead shot produces even patterns that crush clays. These loads also feature consistent, reliable Federal primer; an eight-segment crimp; and an unique wad column for consistent patterns.
Federal ammunition can be found at dealers nationwide or purchased online direct from Federal. For more information on all products from Federal or to shop online, visit www.federalpremium.com.

Irvine, CA — January 25, 2021 — Silynx Communications is excited and proud to announce the launch of FORTIS, a smart, modular tactical headset system that offers users the flexibility to utilize almost any headset and communication device to fit most any operating profile. It is the long-awaited successor to Silynx’s flagship C4OPS and is ideal for elite military teams all over the world. Acting as a central communications hub, the ambidextrous Fortis push-to-talk (PTT) control box offers a two-radio solution with an onboard power, and a three-radio/four-channel solution that also offers an in-line battery option. All models include interface ports to connect FORTIS to a variety of headsets from Silynx or other manufacturers – in-ear, over-the-ear, acoustic tubes, music earbuds – as well as to many communications devices, radios, smartphones, intercom systems, and mesh radios via secure onboard metal connectors. Fortis adapts to virtually any operational profile and team preference.
Silynx Communications not only called upon its vast engineering expertise but also its industrial- design experience to create a unique, modern fluted design that is slightly tapered to conform to a user’s grip. And Fortis’ protective outer housing can be easily changed out—an industry first—and fitted with most any custom color, pattern, or team insignia. Or it can be easily changed out in the unlikely event that the housing gets damaged.
Fortis is the most advanced, adaptable communication system on the market. Its durability— including integrated onboard connectors—flexibility, and quality are simply unmatched, and it is water- submersible up to 20 meters. And, when paired with Silynx in-ear earpieces, it also boasts superior hearing protection, both passive and active, to keep users safe.
“FORTIS does have it all. We brought together all our expertise to pack it full of technology that functions effortlessly, dependably, and integrates with most any device and configuration imaginable. We have always stood alone in our attention to function and form. The FORTIS control box has a unique industrial design, which incorporates an industry-first user-changeable external housing. Our customers for Fortis are primarily elite military teams who operate to adjacent commands with multiple radios. We take that responsibility seriously and are proud of what we provide to them. They do the hard, important work.” said Matthew Hemenez, President of Silynx Communications.
A revered Naval Special Warfare group was first in line to put Fortis to the test. The excellence of their team—and the demands of their operations—are legendary. That said, we know all operations are filled with the high stakes and this made us thankful to be put to the test with their great team. In the coming months, if permitted, we’ll share more of their stories and feedback, so everyone can learn from their initial experiences with Fortis.
Fortis models are now available for Testing & Evaluation (T&E).

The Descent Mk2i is Garmin’s latest watch-style dive computer. It pairs with Garmin’s Descent T1 transmitter via Garmin SubWave, which is a sonar-based communication protocol, to send tank pressure data right to the diver’s wrist.
The Mk2i can accept data from up to five paired Descent T1 transmitters, offering tank pressure, air time remaining, gas consumption rate to monitor other divers or additional tanks within a 10-meter range.
The dive computer function supports multiple dive modes for single and multiple gas dives (including nitrox, trimix and 100% O2), gauge, apnea, apnea hunt and closed circuit rebreather. It also features an underwater 3-axis compass and display depth, dive time, temperature, NDL/TTS, ascent/descent rates, gas mix, PO2, N2 loading, decompression/safety stop information, and time.
You can also share and review up to 200 dives via the Garmin Dive app.
Featuring a 1.4-inch sunlight-readable color display, it’s also a GPS watch for use on the surface. Garmin’s GPS watch features are well known. Anymore, it’s more a matter of what it won’t do rather than talking about what it does. However, we’ll quickly review.
First off is Global Navigation Satellite System connectivity which includes GOS, GLONASS and Galileo. You get position data, turn by turn navigation and round trip routing. There are also Garmin’s classic ABC sensors, including an altimeter for elevation data, barometer to monitor weather and 3-axis compass.
You also get advanced training metrics which include running dynamics, heat- and altitude-adjusted VO2 max, recovery advisor and more. There are also preloaded activity profiles for trail running, swimming, running, biking, hiking, rowing, skiing, and golfing.
Your watch will also guide your workout with animated workouts for cardio, strength, yoga and Pilates. Additionally, PacePro technology helps keep you on pace with grade-adjusted guidance as you run a course.
Respiration, pulse ox and heart rate monitors are all embedded in the Descent Mk2i. And, there are always more apps being added.
What’s more, the Descent Mk2i can be connected to a Garmin inReach satellite communicator at the surface so you can send and receive messages from watch and even trigger an interactive SOS.
Expect about 16 days of battery life from the Descent Mk2i in smartwatch mode and up to 80 hours in dive mode. It has a battery life of up to 32 hours when paired with a Descent T1. The T1 transmitter is depth rated to 11 ATM10 and has a battery life of up to 110 hours of diving with a user-replaceable CR123 battery.
