A breakthrough in neurotechnology has emerged as a team of Chinese researchers, led by the Institute of Automation under the Chinese Academy of Sciences, unveiled the world's first battery-powered, wearable repetitive transcranial magnetic stimulation (rTMS) device. Weighing only 3 kilograms – lighter than many laptops – and consuming just 10 percent of the power required by traditional machines, this innovative device is set to transform mental health therapy by enabling high-frequency brain stimulation during free movement.
Traditional rTMS devices have been confined to fixed clinical settings, often weighing over 50 kilograms and limiting patient accessibility. The new portable design employs lightweight magnetic core coil technology, along with high-power-density and high-voltage pulse driving techniques, which allows for dynamic neural modulation even during activities such as walking. Early trials revealed that leg movement can enhance arm-related brain activity, offering fresh insights into human neural interactions.
Beyond its immediate applications for neuropsychiatric disorders like depression, stroke rehabilitation, and addiction, this breakthrough opens the door to integrating non-invasive brain signal detection technology. Senior engineer Liu Hao highlighted the potential for a wearable closed-loop rTMS neuromodulation system, which could transition brain-computer interfaces from laboratory settings to practical, everyday use.
This development not only promises more accessible at-home and community-based therapies but also serves as a testament to the power of innovation in tackling chronic health conditions. As mental health care continues to evolve globally, such advancements resonate with a diverse audience eager for sustainable, tech-driven solutions that enhance quality of life.
