Google Glass monitors heart and breathing in real time

A paper released this week by MIT Media Lab and Georgia Tech researchers claims that Google Glass can detect pulse and respiration rhythms in real time.  The responses were measured using a built-in gyroscope, accelerometer and camera, with no external sensors. According to lead author Javier Hernandez, “Glass detects these physiological indicators with a very high accuracy when compared […]

Face video scan detects heart disease

According to University of Rochester professor Jean-Philippe Couderc, cardiac disease can be identified and diagnosed using contactless video monitoring of the face. A recent study describes technology and an algorithm that scan the face and detect skin color changes imperceptible to the naked eye. Sensors in digital cameras record the colors red, green, and blue. Hemoglobin  “absorbs” […]

50 Cent/Intel headphones combine music and health

Following Dr. Dre‘s enormously successful Beats by Dre,  celebrities are entering the wearable/headphone market,  combining audio with health/fitness monitoring features. Intel and rapper 50 Cent, through his SMS Audio venture,  have announced a partnered to develop BioSport headphones.   Their key feature is a series of biometric sensors integrated into a custom heart rate monitor.  An […]

Google Glass software provides visual feedback in surgery

A challenge in surgical training is facilitating an attending surgeon’s visual feedback to residents conducting operations.  CrowdOptic‘s software lets one Google Glass wearer receive another’s point of view by looking in the other user’s direction.   It is being used in the Department of Cardiothoracic Surgery at Stanford University Medical Center to improve resident training in complex […]

Sensor seatbelt detects fatigue

HARKEN is a sensor embedded  driver’s seatbelt and seat cover that monitors cardiac and respiratory rhythms.  Its hidden signal processing unit analyzes the data in real time.  The prototype is being developed at Spain’s  Biomechanics Institute in Valencia. When the sensor data indicates the person is falling asleep, an alarm will wake the driver.  Closed track testing […]

Self powered piezoelectric pacemaker

KAIST professor Keon Jae Lee and Yonsei University professor Boyoung Joung have developed a self-powered artificial cardiac pacemaker operated semi-permanently by a flexible piezoelectric nanogenerator. The flexible piezoelectric nanogenerator directly stimulated a living rat’s heart using electrical energy converted from body movements. This could facilitate the use of self-powered flexible energy harvesters,  prolonging the life of cardiac pacemakers […]

Custom fitted, 3D printed, sensor based, implantable cardiac device

Nature paper |  Washington University | University of Illinois A custom-fitted, implantable device with embedded sensors, while invasive, may offer an improved method for detecting and treating heart issues. Washington University professor Igor Efimov and University of Illinois professor John Rogers (see previous ApplySci Rogers coverage) have created a 3-D elastic membrane made of a soft, flexible, silicon material that is precisely […]
