Smart bandage continuously measures pH and oxygen

Harvard professor Ali Khademhosseini, a doctor at Brigham and Women’s Hospital, is developing a smart bandage that determines a wound’s healing progress and distributes medicine accordingly. The prototype bandage looks like rubber, and has visible sensors tracking pH balance (for bacterial infection), and oxygen, automatically delivering oxygen or antibiotics topically.  Diabetic foot ulcers might be better treated this […]

Tiny robotic gripper for cancer diagnostics, remote surgery

Johns Hopkins professor David Gracias has created a tiny, flexible, microscopic, robotic,  hand-like hydrogel gripper that could help doctors perform remotely guided surgical procedures and biopsies.    He believes that the materials could also, in the future,  deliver therapeutic drugs to difficult to reach places. The hydrogel can swell in response to changes in temperature, acidity or light, providing […]

Smartphone tests detect Parkinson’s

In a recent study,  MIT Media Lab‘s  Max Little used machine learning tools to indicate early Parkinson’s Disease in a group of smartphone users.  Phones were given to Parkinson’s patients and a healthy control group. The built in accelerometer enabled Little to distinguish between those with and with out the disease with  99% accuracy.  The detection method relied […]
