Electronic Textiles for Motion Analysis

by Edmison, Joshua Nathaniel

The union of electronics and textiles to form electronic textiles (e-textiles) provides a promising substrate upon which motion analysis applications can be developed and implemented. Familiarity with clothing allows sensors and computational elements to be naturally integrated into garments such that wearability and usability is preserved. The dynamics of the human body and the wide variety of sensor and processing choices render the typical prototype-based design methodology prohibitively difficult and expensive. Simulation of e-textile systems not only reduces these problems but allows for thorough exploration of the design space, faster design cycles, and more robust applications. Gait analysis, the measurement of various body motion parameters during walking for medical purposes, and context awareness, the recognition of user motions, are two immediate applications that e-textiles can impact and emphasize the feasibility of e-textiles as a medium for sensor deployment on the human body. This thesis presents the design of a simulation environment for wearable e-textile systems and demonstrates the use of the simulation via a prototype pair of e-textile pants.
