ESi’s biomechanical engineering consultants specialize in analyzing the body’s response to forces and accelerations in diverse environments. Our expertise spans transportation, industrial, construction, manufacturing, and agricultural sectors, addressing cases involving motor vehicle accidents, product liability, and workplace injuries.
Our multidisciplinary approach includes full-scale crash testing and collaboration with our accident reconstruction experts to analyze factors like seatbelt use, airbag deployment, helmet effectiveness, and child restraint systems. Our team of medical doctors, forensic pathologists, and forensic nurses enhance our investigations, ensuring robust analyses that bridge engineering and medical perspectives.
Using advanced tools like motion capture, wearable sensors, anthropomorphic test dummies (ATDs), and computer simulations, our team reconstructs incidents by collaborating across technical disciplines, providing critical insights for both civil and criminal litigation. Our capabilities also include video analysis, surrogate testing, and ballistic evaluations, ensuring comprehensive assessments of injury mechanics and human performance limits.
ESi’s biomechanics team applies its expertise across a wide range of applications, including sports equipment, automotive safety, and household products. We tailor our methodologies to address client-specific needs, delivering actionable, evidence-based findings that guide litigation strategies, enhance safety, and mitigate risks.
