”Wind Walker” to fill the industry gap The first domestic intelligent power calf prosthesis “Wind Walker” launch conference was held in Zhengzhou recently, which marks the official launch of China’s first intelligent below-knee prosthetic products. This product is led by Wang Qining, director of the Intelligent Systems and Human Engineering Laboratory at Peking University’s College of Engineering, who led the research and development. The whole structure of “Windwalker” contains sensors, computer chips and electromechanical devices, which can highly simulate the functions of biological nerves, brain and musculoskeletal tissues. At present, the field of intelligent prosthesis is mainly monopolized by foreign manufacturers such as Iceland Orso, “Windwalker” listed to fill the gap in the industry of domestic below-knee intelligent prosthesis. Flash tracks exercise and sleep data Misfit of San Francisco, California, recently released a new product, Misfit Flash, which can track the wearer’s exercise and sleep. The device automatically tracks steps, calories burned, distance, sleep quality time and cycles. The device can be worn as a wristband or attached to pants, shirts, shoes and on a keychain. The Flash can be synchronized wirelessly with the Misfit App on Apple or Android devices, and Sonny Vu, one of the founders of Misfit, has hinted that the company will not only develop sports and sleep monitoring, but will also move into medical devices. Brain scan for rapid diagnosis of ADHD British researchers have found that the brains of children with ADHD develop relatively slowly compared to other young children of the same age. The new findings will allow doctors to use brain scans to diagnose ADHD and monitor how patients respond to treatment. The findings will also help researchers understand how ADHD develops from childhood to adulthood. Some children heal spontaneously, and some children continue to have ADHD into adulthood. Dr. Chandra Sripada of the Department of Psychiatry at the Medical College of Michigan says studying the maturation of brain networks in children with ADHD will help explain this phenomenon. ”Electronic skin” senses breast lumps Researchers at the University of Nebraska have developed an “electronic skin” that can sense and image small lumps in the breast, which may provide some early insight into the detection and identification of breast cancer. This may provide some early research basis for breast cancer detection and identification. The researchers embedded lump-like objects into silicone simulated breast tissue and then used the “electronic skin” to detect them. In the future, this new device may help researchers to conduct early diagnostic screening for breast cancer risk patients in order to achieve early treatment purposes. New device monitors Parkinson’s motor symptoms A personal KinetiGraph, a wearable device for monitoring and treating Parkinson’s disease, has received FDA clearance. Monitoring changes in a patient’s motor symptoms is key to the treatment of Parkinson’s and other movement-related diseases, and the Personal KinetiGraph provides clinicians with a clear and accurate assessment of a patient’s condition beyond the examination. The Personal KinetiGraph can collect and store up to 10 days of movement data. The shorthand can be downloaded by the physician for more accurate assessment of the patient’s motor abilities. The device can also be used as a medication adherence tool with levodopa, a symptomatic treatment for Parkinson’s, and can be set to vibrate a preset number of times to remind patients to take their medication on time. Small lens helps upgrade phones to microscopes Researchers at the Garvan Institute of Medical Research and National University in Australia say it takes just a lentil-sized lens to upgrade a smartphone to an ultra-high-pixel microscope for high-level medical image viewing. Made of the same material as contact lenses and breast implant fillers, the lens polymer can be used to seal bathrooms, and the polymer itself is less likely to be damaged or scratched. When mounted on a smartphone or tablet with a flash, these lenses can magnify 160 times and see up to 4 microns.
