Field evaluation of a wearable instrumented headband designed for measuring head kinematics
Anu Tripathi, Yang Wan, Zhiren Zhu +11
Purpose: To study the relationship between soccer heading and the risk of mild traumatic brain injury (mTBI), we previously developed an instrumented headband and data processing s…
Determining the acceleration field of a rigid body using three accelerometers and one gyroscope, with applications in mild traumatic brain injury
Yang Wan, Benjamin E. Grossman-Ponemona, Haneesh Kesari
Mild traumatic brain injury (mTBI) often results from violent head motion or impact. Most prevention strategies explicitly or implicitly rely on motion- or deformation-based injury…
Approximating a matrix as the square of a skew-symmetric matrix, with application to estimating angular velocity from acceleration data
Yang Wan, Benjamin E. Grossman-Ponemona, Haneesh Kesari
In this paper we study the problem of finding the best approximation of a real square matrix by a matrix that can be represented as the square of a real, skew-symmetric matrix. Thi…
Cracking in polymer substrates for flexible devices and its mitigation
Anush Ranka, Madhuja Layek, Sayaka Kochiyama +11
Mechanical reliability plays an outsized role in determining the durability of flexible electronic devices because of the significant mechanical stresses they can experience during…
Laboratory evaluation of a wearable instrumented headband for rotational head kinematics measurement
Anu Tripathi, Yang Wan, Sushant Malave +8
Mild traumatic brain injuries (mTBI) are a highly prevalent condition with heterogeneous outcomes between individuals. A key factor governing brain tissue deformation and the risk…
The mechanics of the squash nick shot
Mithun Ravisankar, Madeline Federle, Mina Bahadori +3
Squash is a widely popular racket sport, practiced by millions of people worldwide, played inside a walled court. When played well, players can last for several minutes before the…
