Gait impairment, or difficulty with walking, is a major liability for stroke and Parkinson's patients. A new wearable electronic device that can be inserted inside any shoe may be able to address this challenge. The researchers presented their work in the paper, "Flexible Smart Insole and Plantar Pressure Monitoring Using Screen-Printed Nanomaterials and Piezoresistive Sensors." "I'm trying to bridge the gap between the lack of available devices in hospitals or medical practices and the lab-scale devices," Yeo said.
