Adaptive flooring tiles for hospitals aimed at reduction of fall injuries

About 2 million patients are injured at Hospitals across the United States Only. The flooring is mostly plain Vinyl Composition Tile, which is ceramic based which does not provide any resistance to random falls. Most of these injuries occur among elderly patients being treated for an ailment and this adds to their recovery process. This project aims to design and propose a system of flooring with shock absorbing material, which leads to increase in time of impact thereby reducing the impact force on patients subjected to random falls. Simulation involves explicit dynamic analysis using ANSYS Workbench of the different systems and empirical lab testing using force plates is underway to explore more into this idea.

Slips: characterization of contributing factors associated with footwear, floor surfaces, and gait using a robotic testbed.

The world’s population is living longer, and the average age of workers in the US is increasing. Adults 65 and older are at an increased risk of injury from falls. Injuries from falls often lead to limited activity, reduced mobility, and a fear of falling, all of which increase risk of additional injury. Slips and falls are recognized as a major threat to the safety of individuals not only in industry, but also in daily living.

The purpose of this study is to quantify the effects of footwear, floor surface characteristics and modified gait trajectories and their contributions to slips using a robotic testbed. It pursues three aims: (1) Investigate the role that footwear has in predicting slip, (2) Examine the role that flooring surface conditions have in predicting slip, (3)Characterize how gait changes associated with age modify the interaction between footwear and flooring surfaces, and subsequent slip potential.  There are three hypothesizes: (1) footwear plays a significant role in slip and fall injuries, (2) terrain and flooring surface conditions modify slip and fall potential and (3) gait changes associated with age contribute to increased slip and fall parameters and are modified by footwear and floor/terrain conditions.
