Tiny sensor monitors the heart, recognizes speech, enables human-machine interfaces

Northwestern professor John Rogers has released a paper detailing his latest tiny, wearable, flexible, highly accurate health sensor, which monitors the heart, recognizes speech, and can enable human-machine interfaces.  Professor Yonggang Huang is the corresponding author. The soft, continuous monitor adheres to any part of the body, detecting mechanical waves that propagate through tissues and fluids […]

Voice analysis as a diagnostic tool

Beyond Verbal recently used its emotion-detecting voice analysis app in an attempt to predict coronary artery disease in 150 study participants, 120 of whom had presented for angiography.  The company claims to have identified 13 voice features  associated with CAD – and one associated with a 19-fold increase in its likelihood. The researchers said that […]

Verily developing low-power health wearable

While visiting Verily last week, an MIT Technology Review journalist saw and described the company’s wearable vital tracker, called the “Cardiac and Activity Monitor” by  CTO Brian Otis.  Its novelty is a low-power e-paper display, which will address the universal problem of battery life.  Only with guaranteed continuous measurement can meaningful data be gathered and health analyzed. The […]

Electronic scaffold replaces damaged tissue, stimulates heart

Charles Lieber and Harvard colleagues have designed nanoscale electronic scaffolds, seeded with cardiac cells to produce a “bionic” patch to replace damaged cardiac tissue.  The flexible electronics can also electrically stimulate the heart, and change the frequency and direction of signal propagation, as tissue feedback is continuously monitored. Instead of being located on the skin’s […]

Wearable detects cardiac arrest, notifies emergency services

 iBeat is a wearable emergency response system that continuously monitors the heart.  Meant for seniors, it detects cardiac arrest in real time, provides alerts, and sends regular updates to caregivers. If cardiac arrest is detected, the wearer receives a call within 10 seconds.  If he/she cannot be reached, an emergency contact and emergency medical services […]

Wearable patch simultaneously monitors biochemical, electric signals

Joe Wang and Patrick Mercier of UCSD have developed a flexible, wearable, patch that monitors both biochemical and electric signals. Most  wearables only measure one parameter, such as steps or heart rate, and few measure chemical signals. The Chem-Phys patch records EKG signals, and tracks lactate levels, marking physical effort, in real time.  It  is worn on […]
