Small, foam hearable captures heart data

FacebooktwitterlinkedinFacebooktwitterlinkedin
In a small study, Danilo Mandic from Imperial College London has shown that his hearable can be used to capture heart data. The device detected heart pulse by sensing the dilation and constriction of tiny blood vessels in the ear canal, using the mechanical part of the electro-mechanical sensor. The hearable is made of foam and molds to the shape of the ear. The goal is a comfortable and discreet continuous monitor that will enable physicians to receive extensive data. In addition to the device’s mechanical sensors, Mandic, a signal processing experter, claims that electrical sensors detect brain activity that could  monitor sleep, epilepsy, and drug delivery, and be used in personal authentication and cyber security.

Small, adhesive, wireless patch collects, transmits, extensive health data

FacebooktwitterlinkedinFacebooktwitterlinkedin

Northwestern’s John Rogers and Kyung-In Jang of the Daegu Gyeongbuk Institute of Science and Technology have developed a small, adhesive, flexible silicone patch capable of monitoring multiple health parameters.

The soft, body-conforming wearable contains 50 components connected by  250  3-D wire coils embedded in protective silicone.  It collects and wirelessly transmits data about movement, respiration, and  electrical activity in the heart, muscles, eyes and brain.

Jang believes that the biosensors could be devloped into a closed loop medical system using big data and AI, and thereby facilitate quality remote healthcare. The team is also exploring the use of the patch in robotics and self-driving cars.

Professor Rogers will present his research at ApplySci’s upcoming Wearable Tech + Digital Health + Neurotech conference, on September 19th at the MIT Media Lab.

Hypoallergenic, continuous, week-long health wearable

FacebooktwitterlinkedinFacebooktwitterlinkedin

University of Tokyo professor Takao Someya has developed a hypoallergenic, adhesive, continuous health sensor. The device can be worn comfortably for a week because of its nanoscal mesh elastic electrodes.  This allows the skin to breathe, preventing inflammation.

The electrodes contains a  biologically compatible,  water-soluble polymer, polyvinyl alcohol, and a gold layer. The wearable  is applied by spraying a tiny amount of water, which dissolves the PVA nanofibers, and allows it to stick easily to the skin. It conforms to curvilinear surfaces of human skin, such as sweat pores and the ridges of an index finger’s fingerprint pattern.

A study of 20 subjects wearing the device showed that  electrical activity of muscles were comparable to those obtained through conventional gel electrodes.  There was no inflammation after one week, and repeated bending and stretching did not cause damage, making this a potentially disruptive method to monitor health and performance.

Adhesive patch + nose wearable detect sleep apnea

FacebooktwitterlinkedinFacebooktwitterlinkedin

Somnarus has developed a disposable, adhesive patch that detects obstructive sleep apnea at home.

The SomnaPatch is worn on the forehead, wth an addtional piece on the nose. It records nasal pressure, blood oxygen saturation, pulse rate, respiratory effort, body position and how long a patient is asleep.

An 174-patient study showed that results from the SomnaPatch matched standard in-lab polysomnography 87% of the time.

If the device is proven effective in larger studies, it could be a cheaper, more comfortable alternative to lab-based sleep studies.

Earbud sensor reportedly measures blood pressure, dehydration

FacebooktwitterlinkedinFacebooktwitterlinkedin
As health sensors become more discreet, and fused with commonly worn devices, Kyocera has integrated a tiny, optical sensor into its earbud.  The hybrid music/phone/health use wearable measures blood flow in hypodermal tissues using Laser Doppler velocimetry. It can monitor nerve and blood pressure, levels of dehydration, and possible signs of heat stroke.  Sleep monitoring can be done more accurately than with current devices, and the effect of music on brain states can also be studied.

Sweat sensor for cystic fibrosis detection, drug optimization, glucose monitoring

FacebooktwitterlinkedinFacebooktwitterlinkedin

Carlos Milla, Ronald Davis, and Stanford and Berkeley colleagues have developed a wearable sweat sensor for detecting cystic fibrosis, diabetes and other diseases.  It can also aid drug development and personalization, and continuously monitor patients.

The flexible sensor/microprocessor system adheres to the skin, stimulates sweat glands, and detects the presence of molecules and ions based on electrical signals.  Increased chloride generates increased electrical voltage at the sensor’s surface.  High levels of chloride ions indicate cystic fibrosis.

Conventional methods for diagnosing cystic fibrosis require a visit to a specialized center, where a patient does not move for 30 minutes, while electrodes stimulate their sweat glands. A lab then measures chloride ions in the sweat to diagnose the disease. This method hasn’t changed in 70 years.

The wearable sweat sensor stimulates skin to produce minute amounts of sweat, quickly evaluates the contents, and sends the data via phone, to the cloud, for immediate analysis.   The system is portable and self-contained, and ideal for use in children, and in underserved communities.

As CF is caused by hundreds of different mutations in the CF gene,  it’s possible to use the sensor to determine which drugs work best for which mutations.

The device was also used to compare levels of glucose in sweat to that in blood.

Verily’s health sensing research watch

FacebooktwitterlinkedinFacebooktwitterlinkedin

The  Verily Study Watch passively captures health data for continuous care platforms and clinical research. Key features described by the company include:

  • Multiple physiological and environmental sensors are designed to measure relevant signals for studies spanning cardiovascular, movement disorders, and other areas. Examples include electrocardiogram (ECG), heart rate, electrodermal activity, and inertial movements.
  • A long battery life of up to one week in order to drive better user compliance during longitudinal studies.
  • Large internal storage and data compression allow the device to store weeks’ worth of raw data, thus relaxing the need to frequently sync the device.
  • A powerful processor supports real time algorithms on the device.
  • The firmware is designed to be robust for future extensions, such as over-the-air updates, new algorithms, and user interface upgrades.
  • The display is always on so that time is always shown. The display is low power and high resolution for an appealing look and a robust user interface. Note: currently, only time and certain instructions are displayed. No other information is provided back to the user.

The watch will be used in Verily’s current and forthcoming studies, such as the  Personalized Parkinson’s Project, meant to track progression, and the Baseline study, meant to understand transitions between health and disease.

Apple reportedly developing non-invasive glucose monitor

FacebooktwitterlinkedinFacebooktwitterlinkedin

CNBC’s Christina Farr has reported that Apple has been quietly developing a non-invasive, sensor-based glucose monitor.  The technology has apparently advanced to the trial stage.

Diabetes has become a global epidemic.  Continuous monitoring, automatic insulin delivery, and the “artificial pancreas” are significant steps forward, meant to control the disease, and avoid its debilitating side effects.  While some systems consist of micro-needles just below the skin, to date, none are totally non-invasive.

The ideal solution would be the use of the Apple Watch and other fitness/lifestyle trackers to control behavior to the point that the disease is avoided entirely.  However, if diagnosed, a non-invasive glucose sensor would transform the daily life of diabetics.

Future hearable sensors could track physical, emotional state

FacebooktwitterlinkedinFacebooktwitterlinkedin

Apple has filed patent applications describing wireless earbuds that monitor health while a wearer talks on the phone or listens to music.  This has obvious exercise-related implications, but could potentially track the physiological impact of one’s emotional state while making calls, as a mobile mental health tool.

Sensors included in the patent include EKG, ICG, VO2 and GSR.
