LSU Researcher Develops Innovative Exoskeleton for Construction Safety

A third-year doctoral student at Louisiana State University (LSU) has developed an innovative exoskeleton aimed at enhancing safety and reducing fatigue for construction workers. M.G. Taylor, a graduate research assistant in the textiles, apparel design, and merchandising program, collaborated with the construction engineering program on this project, which addresses a critical need in the industry.

The exoskeleton, designed as personal protective equipment (PPE), aims to support workers throughout their demanding tasks on construction sites. Taylor highlighted the significance of this design, stating that repeated stress injuries often force workers to end their careers prematurely. “The exoskeleton is a two-part system,” Taylor explained. “On top, we have a harness that holds the exoskeleton in place, and we had to figure out how to distribute the weight over the trunk and shoulders.”

The design team created a backpack-like pouch for the electronic motor located in the lower half of the exoskeleton. Following several redesigns, they completed the lower body prototype, which features breathing holes made from polylactic acid filament, extending from the thigh to the ankle. Taylor noted, “We’re about to print a prototype using a carbon fiber integrated filament, which will provide greater strength for its intended purpose: protection.”

The researchers utilize modeling software called CLO, which functions similarly to computer-aided design software but specifically for fashion applications. This allows them to create 3D clothing designs, work through multiple iterations, and finalize the components before proceeding to laser-cutting, heat-bonding, and sewing.

User testing is the next crucial step in the development process. Taylor emphasized the importance of ensuring that the exoskeleton meets the needs of its users. “Why design something if it doesn’t work for its users?” she asked. Many existing PPE options do not fit well, prompting the team to develop gear that is not only functional but also comfortable for daily use.

Taylor pointed out that the construction industry has only recently begun to cater to a wider range of body types, particularly for women. “For years, many users had to wear an extra belt to ensure proper fit, which can be dangerous if it gets caught in machinery,” she said. This highlights a pressing issue in construction safety, where ill-fitting equipment can lead to severe injuries.

The exoskeleton is anticipated to have applications beyond construction, including fields such as petroleum engineering. Blake Samson, a freshman in petroleum engineering from Maumelle, Arkansas, expressed enthusiasm for the design, stating that the motor function could significantly reduce fatigue and prevent accidents associated with physical weakness. “Heavy machinery is nothing to mess with,” he cautioned. “Someone struggling to walk after a long day could be at risk of a potentially fatal incident near powerful equipment.”

While the complete exoskeleton may be costly, the proposed ownership model involves workers retaining the upper vest portion, while construction companies would provide the lower half, including the motor. Taylor concluded, “We’re able to bring construction, engineering, and fashion together in a meaningful way — that is a unique team poised for success.”

As the project progresses, the integration of safety and innovation continues to be at the forefront of Taylor’s work, potentially transforming the landscape of personal protective equipment in the construction industry.
