App optimizes meditation length to improve attention and memory

Adam Gazzaley and UCSF colleagues have developed a focus-driven digital meditation program that improved attention and memory in healthy adults in a recent study. MediTrain tailors meditation session length to participant abilities, and challenges users to increase session time. Subjects received significant benefits in 6 weeks.  On their first day, they focused on their breath […]

Sensor glove identifies objects

MIT’s Subramanian Sundaram has developed a sensor glove that identifies objects through touch.  This could improve assistive robot performance and enhance prosthetic design.The cheap “scalable tactile glove” includes 550 tiny, pressure-capturing sensors.  A neural network uses the data to classify objects and predict their weights.  No visual input is required. In a Nature paper, the system […]

Study: Noninvasive BCI improves function in paraplegia

Miguel Nicolelis has developed a non-invasive system for lower-limb neurorehabilitation. Study subjects wore an EEG headset  to record brain activity and detect movement intention. Eight electrodes were attached to each leg, stimulating muscles involved in walking.  After training, patients used their own brain activity to send electric impulses to their leg muscles, imposing a physiological gait. With […]

Atrial fibrillation-detecting ring

Eue-Keun Choi and Seoul National University colleages have developed an atrial fibrillation detecting ring, with similar functionality to AliveCor and other watch-based monitors. The researchers claim that the performance is comparable to medical grade pulse oximeters. In a study, Soonil Kwon and colleagues analyzed data from 119 patients with AF who underwent simultaneous ECG and photoplethysmography […]
