Researchers from Hong Kong and mainland China have developed a lightweight, battery-free neural prosthesis designed to assist individuals with walking difficulties, particularly stroke survivors. This innovative device harnesses the energy produced by the wearer’s movements to electrically stimulate muscles, aiding in ankle flexion and restoring a natural gait.
The device could significantly reduce the risk of falls for stroke survivors, elderly individuals, and others with mobility impairments. Additionally, it has potential applications for athletes during training sessions.
The team noted that instead of depending on external sensors or batteries, the device operates automatically, utilizing energy harvesting from mechanical movement. According to a study published in Nature Communications, the device significantly improved stride length and walking speed in stroke survivors during both treadmill and outdoor walking tests.
