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 …

Maxim Announces Wearable ECG and Heart Monitor Development Kits

Maxim ECG Heart Monitor Development Kits

Maxim Integrated has recently announced two wearable development kits for fitness / health tracking: MAX-HEALTH-BAND watch for vital signs MAX-ECG-MONITOR with a chest strap for clinical-grade electrocardiograph (ECG) and heart rate. MAX-HEALTH-BAND Development Kit The MAX-HEALTH-BAND wrist-worn heart-rate and activity monitor features the company’s MAX86140 optical pulse-oximeter/heart-rate sensor, MAX20303 wearable power-management solution, and Maxim’s motion-compensated algorithms. The watch sends raw PPG and accelerometer data via Bluetooth to a smartphone app, and also monitors steps, activity, heart rate and interbeat intervals for heart-rate variability measurements. Battery life is around 7 days on a single charge. The kit also includes a USB charging cable, and instructions to download the Android-based application. The evaluation platform can be used for the development of fitness and wellness trackers, health monitoring trackers, or as a experimentation platform for new use cases and algorithms. In addition to raw PPG and accelerometer data, the MAX-HEALTH-BAND monitors steps, activity, heart rate, and interbeat intervals for heart-rate variability. The MAX-HEALTH-BAND …

ASUS VivoWatch BP is a Fitness Tracker that Measures Blood Pressure

If you need to monitor your blood pressure regularly, you may have used one of those blood pressure monitors that you wraps around your upper arm, and display results on an LCD display, and in some cases, synchronize the data with your smartphone Bluetooth. Those devices do the job, but they may be inconvenient to use daily, and some people just forgo measurements. Omron first introduced a more user-friendly solution with their Project Zero BP6000 blood pressure monitor-in-a-watch in 2016, further refined with Project Zero 2.0 watch in 2017. That’s all good, except for the same details that neither versions of the watch – to be called Heartvue – are for sale, as the company is still working on FDA approval… ASUS has filled the void with VivoWatch BP watch, and IMHO has taken a more clever approach to launching their product, since the watch will be available in Asia this summer, and in the US after FDA approval, which …

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 …

A Day at Chiang Mai Maker Party 4.0

The Chiang Mai Maker Party 4.0 is now taking place until December 9, and I went there today, as I was especially interested in the scheduled NB-IoT talk and workshop to find out what was the status about LPWA in Thailand. But there are many other activities planned, and if you happen to be in Chiang Main in the next few days, you may want to check out the schedule on the event page or Facebook. I’m going to go though what I’ve done today to give you a better idea about the event, or even the maker movement in Thailand. Booth and activity area should be the same over the 4 days, but the talks, open activity, and workshop will be different each day. Today, people could learn how to solder in the activity area. The even was not really big with manufacturers/sellers like ThaiEasyElec, INEX, or Gravitech closer to the entrance… … and slighter higher up in a …

Review of Koogeek BP2 Bluetooth Blood Pressure Monitor

Koogeek BP2 is an FDA approved smart blood pressure monitor that connects over Bluetooth to your Android or iOS smartphone, or WiFi to the cloud. The company sent me a sample for evaluation, so let’s get started right away. Koogeek BP2 Unboxing The device is sent in a cardboard package with Koogeek brand… and some more derails about the specifications on the bottom of the package. I asked the company to confirm about FDA approval, and they told me to look for K134029 on the FDA website, which lead me to this document testing Shenzhen Belter Health Management and Analysis ePA-46B, and comparing it to the results of Omron HEM-7200-Z (BP742) with the conclusion being that: The Belter Blood pressure meter (ePA-46B) is substantially equivalent to the predicate devices. Koogeek BP2 is the same as Belter ePA-46B, but just rebranded, and with a different mobile app. In the package will find the device with the cuff attached to the main unit …
