"Windwalker" fills the industry gap
China's first intelligent power calf prosthetic "windrunner" listing conference was held in Zhengzhou a few days ago, which marked the official launch of China's first smart knee prosthetic products. This product was developed by Wang Qining, director of the Intelligent Systems and Ergonomics Laboratory of Peking University School of Technology.
The “Windwalker†complete structure consists of sensors, computer chips and electromechanical devices that mimic the functions of biological nerves, brain and musculoskeletal tissue. At present, the field of intelligent prosthetics is mainly monopolized by foreign manufacturers such as Iceland Ossur, and the listing of “windrunners†fills the gap in the industry of artificial prosthetics under the knee.
Flash tracking sports sleep data
Misfit, San Francisco, Calif., recently released a new product, Misfit Flash, to track the wearer's movements and sleep. Flash uses a button battery and does not require charging. The device automatically tracks the number of steps, calories burned, distance, sleep quality time and period. The device is worn with a wrist strap or attached to pants, shirts, shoes and attached to a key chain.
Flash can be wirelessly synced with the Misfit App on Apple or Android devices. Sonny Vu, one of Misfit's founders, hinted that the company will not only develop sports and sleep monitoring, but also enter medical equipment.
Brain scan for rapid diagnosis of ADHD
British researchers have found that children with ADHD have a relatively slow brain development compared to other children of the same age. The new findings allow doctors to use brain scans to diagnose ADHD and monitor patient response to treatment.
The findings also help researchers understand the developmental process of ADHD from childhood to adulthood. Some children will recover automatically, and some children will still have ADHD in adulthood. Dr. Chandra Sripada of the Department of Psychiatry at the Michigan Medical School said that studying the brain network maturity of children with ADHD will find reasons to explain this phenomenon.
"Electronic skin" senses breast mass
Researchers at the University of Nebraska have developed an "electronic skin" that senses small breast masses and images these masses, which may provide early research grounds for breast cancer detection and identification.
The researchers embed a lump-like object in a silicone-simulated breast tissue and then use this "electronic skin" to detect it. The results show that this "electronic skin" can detect and image a lump-like object. The device may help the investigator to screen for early diagnosis of breast cancer risk patients for early treatment purposes.
New equipment to monitor Parkinson's motor symptoms
A personal wearable device for monitoring and treating Parkinson's disease, KinetiGraph, has obtained FDA approval. Monitoring changes in patient motor symptoms is key to the treatment of Parkinson's and other exercise-related diseases. Individual KinetiGraph provides clinicians with a clear and accurate assessment of patient conditions beyond the examination.
Individual KinetiGraph can collect and store 10 days of athletic data. Shorthand can be downloaded by a doctor to more accurately assess a patient's athletic ability. The device can also be used as a drug compliance tool for Parkinson's symptomatic drug levodopa, which can be set up to alert the patient to medication on time.
Small lens helps mobile phone upgrade to microscope
Researchers at the Garvan School of Medical Sciences and National University in Australia say that a lentil-sized lens can be used to upgrade a smartphone to a super-high-resolution microscope for high-level medical image viewing.
Like the materials for contact lenses and breast implant fillers, this lens polymer can be used to seal the bathroom, while the polymer itself is not easily damaged or scratched. When mounted on a smartphone or tablet, with a flash, these lenses can be magnified 160 times and see 4 microns.
