Learn MorePurpose Three-dimensional printed ankle-foot orthoses (AFO) have been used in stroke patients recently, but there was little evidence of gait improvement. Here, we designed a novel customized AFO with energy storage, named Energy-Storage 3D Printed Ankle-Foot Orthosis (ESP-AFO), and investigated its eects on gait improvement in stroke patients.

Learn MoreThe cost per kilowatt-hour for CAES ranges from $150 to $300, while for pumped hydropower it is about $60. A lithium-ion battery would cost $300 a kilowatt-hour and only have a capacity to store energy from one to four hours. With a duration lasting hundreds of hours, sand as a storage medium would cost from $4 to $10 a kilowatt-hour.
