HEGduino IoT Real-time Neurofeedback Platform Aims to Increase Brain Function (Crowdfunding)

The HEGduino Alaskit has developed a way to measure the blood-oxygen levels in the brain and create a biofeedback system that is said to increase brain function. The new tech is called HEGduino and is a connection between a biofeedback method and an IoT platform.  Past Reported Medical SBCs In the past, CNX has covered several health-based platforms for the Raspberry Pi (Healthy Pi HAT) and ESP32 (Hearty Patch, ECG reader) medical SBCs. HEG Particulars The HEG in HEGduino stands for Hemoencephalography, a neurofeedback technique similar to EEG measurements in brainwave activity. The difference is HEG can measure neural activity based on neurovascular coupling, which can be approached through near infrared and passive infrared techniques – both of which are ways to cerebral blood flow can be matched to metabolic activity. HEG Functions The HEG is a way to alter brain function through a series of “training” sessions based on the changes in blood flow to different areas of …

Arm Cortex-A34 is a 64-bit Only Low-Power Core

Arm Cortex-A34

Arm previously announced Cortex-A35 64-bit & 32-bit lower-power CPU core, and later on Cortex-A32 32-bit only Armv8 CPU core with the usual press release, and blog posts providing details about their new offering. But this morning, I saw a tweet about Cortex-A34… Cortex-A34 is an ARM 64-bit only CPU too, and searching about it on Twitter yields zero mentions. Wow. — Longhorn (@never_released) August 2, 2019 Based on the twitter handle, I first assumed it was “never released” ;), and was just an internal part name at Arm. But the new Cortex-A34 was actually very discreetly outed last month when Arm announced Flexible Access to lower the barrier of entry by allowing IC designers to access all Arm IP in the program, and only pay for IP blocks they actually use in the final product. Nevertheless, the product page and developer documentation are now up – albeit with limited info for the latter -, so we have more details. Some …

FOSSASIA 2019 Schedule – March 14-17

FOSSASIA 2019 Schedule

As its name implies, FOSSASIA is a Free and Open Source Software  event taking place every year in Asia, more specifically in Singapore. I first discovered it last year, and published a virtual FOSSASIA 2018 schedule last year to give an idea about the subjects discussed at the event. It turns out FOSSASIA 2019 is coming really soon, as in tomorrow, so I’m a bit late, but I’ll still had a look at the schedule and made my own for the 4-day event.  Thursday – March 14, 2019 10:05 – 10:25 – For Your Eyes Only: Betrusted & the Case for Trusted I/O by Bunnie Huang, CTO Chibitronics Security vulnerabilities are almost a fact of life. This is why system vendors are increasingly relying on physically separate chips to handle sensitive data. Unfortunately, private keys are not the same as your private matters. Exploits on your local device still have the potential to grant bad actors access to your screen …

Self-powered Swallowable Thermometer Measures Internal Body Temperature

Swallowable Thermometer

Having just written about a thermometer board for home automation,  I’ll stay on the temperature measurement topic, as I’ve found another thermometer that targets the medical field instead. Body temperature measurement at my local hospital is done under the armpit, which does the job in most cases, but more accurate temperature measurement of “deep body temperature” is normally achieved through rectal temperature measurement which is not as practical and comfortable for most people. Daily measurements of deep body temperature can apparently allow physicians to better understand “biological clocks”. In practical terms, it means doctors would be able to know ovulation cycles, measure the fatigue degrees of athletes, and even prevent heat strokes and hypothermia. Seeing the impractically in the conventional method, Nakamura Lab at Tohoku University developed a “swallowable thermometer” for this purpose. The swallowable sensor measures just 9.16mm in diameter, is allegedly perfectly safe to the human body, and is powered in the stomach using the same principle as …

Omron HeartGuide Wearable Blood Pressure Monitor is Finally Available

Omron HeartGuide Wearable Blood Pressure Monitor

Way back at CES 2016, Omron showcased Project Zero BP6000 wearable blood pressure monitor that was meant to be an FDA approved blood pressure monitor fitting into a watch form factor and starting to sell for $200 at the end of 2016. But the device was not particularly eye-pleasing and FDA approval is really hard, so they unveiled the thinner and prettier Project Zero 2.0 model the next year at CES 2017 with the goal of releasing the device sometimes in 2018 for $300. The good is that the product – now called HeartGuide – will up for pre-order, and slated to ship in January 2019. Sadly, the cost has gone way up since it now sells for $499, and will only ship to a US address. HeartGuide (BP8000-M) wearable blood pressure monitor technical specifications: Display –  Transflective memory-in-pixel LCD Memory – Blood pressure measurement up to 100 times, activity measurement up to 7 days, sleep measurement up to 7 …

Mediatek Unveils Sensio MT6381 6-in-1 Biosensor Module for Smartphones

Nearly exactly two years ago, Samsung unveiled S3FBP5A bio-processor for fitness tracking wearables with five analog frontends measuring PPG, ECG,skin temperature, BIA, and GSR data, and that is (or was?) expected in the company’s S-Patch3 health tracker. Mediatek has now come up with something with similar functionalities, but instead of being a standalone bio-processor for wearables, Sensio MT6381 biosensor module is designed as a companion chip for smartphones, and capable for delivering 6 different types of heart and fitness data in about 60 seconds. MediaTek Sensio key features and specifications: Integrated R and IR LEDs for reflective PPG measurement + 1-channel ECG analog front-end Health Data Heart-rate in heart beats per minute Heart-Rate Variability (variation in the time between heartbeats). Blood Pressure Trends Peripheral Oxygen Saturation (SpO2) – amount of oxygen in the blood. Electrocardiography (ECG) – electrical activity of the heart over a period of time Photoplethysmography (PPG) – change in volume of blood. I2C /SPI digital interface Dimensions …
