In-sole mems pressure sensing for a lowerextremity exoskeleton
The First IEEE/RAS-EMBS International Conference on Biomedical …, 2006•ieeexplore.ieee.org
The control system for the Berkeley lower extremity exoskeleton (BLEEX) requires ground
contact pressure information to operate safely and effectively. Commercially available in-
sole sensors do not have sufficient bandwidth, accuracy and reliability for such a system. We
have designed and prototyped an in-sole ground contact sensor that uses MEMS pressure
transducers placed in an array of hermetically sealed cavities. This system provides a robust
method to monitor ground contact pressures
