Less invasive, soft tissue artificial retina

Oxford University student Vanessa Restrepo-Schild is developing a synthetic, soft tissue retina that more closely resembles human tissue than current artificial retina technology. Unlike existing implants, the cell-cultures are created from natural, biodegradable materials and do not contain foreign bodies or living entities. This makes the implant less invasive than a mechanical device, and less […]

Transparent, stretchable lens sensor for diabetes, glaucoma detection

UNIST professors Jang-Ung Park, Chang Young Lee and Franklin Bien, and KNU professors Hong Kyun Kim and Kwi-Hyun Bae, have developed a contact lens sensor to monitor biomarkers for intraocular pressure, diabetes mellitus, and other health conditions. Several attempts have been  made to monitor diabetes via glucose in tears.  The challenge has been poor wearability, as the electrodes […]

Wall sensor monitors walking speed, stride to track health

MIT’s Dina Katabi, Chen-Yu Hsu, and colleagues have developed WiGait, a wall sensor that detects walking speed and stride to monitor health. This builds on previous MIT research which showed that radio signals could track breathing and heart rate, without wearables. The  system works by transmitting low-power radio signals and analyzing how they reflect off  bodies within a […]

Tetraplegic patient moves arm with thoughts via BCI/FES system

Bolu Ajiboye and Case Western colleagues used an implanted  BrainGate2 brain-computer interface to allow a tetraplegia patient to control arm movements via an implanted FES muscle stimulation system.  A robotic arm, which was needed in previous BrainGate experiments,  was no longer required. Neural activity was recorded from two 96-channel microelectrode arrays implanted in the motor […]

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

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 […]

Verily’s health sensing research watch

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 […]

CRISPR platform targets RNA and DNA to detect cancer, Zika

Broad and Wyss scientists have used an RNA-targeting CRISPR enzyme to detect  the presence of as little as a single target molecule. SHERLOCK (Specific High Sensitivity Enzymatic Reporter UnLOCKing) could one day be used to respond to viral and bacterial outbreaks, monitor antibiotic resistance, and detect cancer. Demonstrated applications included: Detecting the presence of Zika virus in […]

Apple reportedly developing non-invasive glucose monitor

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. […]

VR therapy could reduce acute and chronic pain

Cedars-Sinai’s Brennan Spiegel has published a study showing that VR therapy could reduce acute and chronic pain. 100 gastrointestinal, cardiac, neurological and post-surgical pain patients with an average pain score of 5.4 were included.  Fifty patients watched a 15-minute nature video. Fifty patients watched a 15-minute animated game with VR goggles. The patients who watched […]
