Omron Project Zero 2.0 is a Thinner Wrist Blood Pressure Monitor & Smartwatch

Omron Project Zero BP6000 blood pressure monitor & smartwatch / fitness tracker was unveiled at CES 2016. The device was due to be released at the end of 2016 pending FDA approval, but the launch has now been delayed to spring 2017, and it will be sold under the name “HEARTVUE”. The company has however showcased a new version at CES 2017, for now just called Omron Project Zero 2.0 that has the same functions but is more compact and lightweight. The watch will also work with Omron Connect US mobile app, and can record accurate blood pressure, as well as the usual data you’d get from fitness trackers including activity (e.g. steps) and sleep, as well as smartphone notifications. Blood pressure measurement can be activated by the user by pressing a button and raising his/her wrist to the height of the chest. The goal is the same as the […]

Mediatek MT2533D is a Bluetooth 4.2 SiP for Smart Headphones & Hands-Free Systems

There used to be a time when most products were based on a general purpose MCU or processor that you would interface to over chips like audio codecs, memory chips, flash storage, etc…, but in order to cut costs, application specific SoCs have become quite common over the year, so we’ve had mobile application processors for several years already, but more recently we got “wearables” SoCs and “Smart Home” SoCs, and Mediatek has launched MT2533D “headphone” SiP (System-in-Package) combining a Cortex-M4 MCU, 4MB PSRAM, an audio codec, and a dual mode Bluetooth subsystem. Mediatek MT2533D specifications: MCU –  ARM Cortex-M4 @ up to 208MHz with 32KB L1 cache, FPU, MPU, AES 128/192/256 crypto engine and TRNG Memory – 160kB SRAMs, 4MB pseudo SRAM Storage – 4MB flash Wireless Connectivity – Bluetooth 4.2 dual mode (classic and low energy) Audio AAC/SBC for Bluetooth audio CVSD/mSBC for Bluetooth speech PCM playback: 8-48kHz […]

Batteryless, Urine Powered Smart Diapers Notify You When It’s Time to Change Them

One of the downside with current smart wearables is that most need to be recharged quite often, every day, week or month, and we’re still a long way of 10 year battery life offered by typical watches. I’m hopefully that eventually many devices won’t need to be recharged at all as we’ll have made improvements both in terms of power efficiency and energy harvesting using solar, body heat, vibrations and other techniques. Takakuni Douseki, professor at the Department of Electronic and Computer Engineering of Ritsumeikan University, has been working on micro energy harvesting, and his latest “wireless involuntary urination sensor system” notifies the user when it’s time change the diapers without the need of any battery, instead using energy generated by urine and stored in a capacitor in order to transmit the data wirelessly. The prototype is using a modified baby diaper with a 320x5mm activated carbon piece, and a […]

Ambiq Micro Introduces Ultra-Low Power Apollo 2 Cortex-M4F MCU Consuming Less than 10 μA/MHz

Last year Ambiq Micro unveiled their Apollo Cortex-M4F MCU with Cortex M0+ energy efficiency thanks to operation in sub-threshold voltage (< 0.5 V), and the MCU is said found in Matrix Powerwatch, a fitness tracker powered by body heat that you never need to charge. The company has recently announced a new version of the micro-controller with Apollo 2 MCU with better maximum performance thanks to a higher maximum clock speed (48 MHz vs 24 MHz), and higher efficiency (10 μA/MHz vs 30 μA/MHz @ 3.3V). Apollo 2 MCU key features and specifications: Ultra-low supply current <10 μA/MHz executing from flash at 3.3 V <10 μA/MHz executing from RAM at 3.3 V ARM Cortex-M4 Processor up to 48 MHz with FPU, MMU, wake-up interrupt controller with 32 interrupts Ultra-low power memory Up to 1 MB of flash memory for code/data Up to 256 KB of low leakage RAM for code/data […]

Tizen Studio 1.0 Replaces Tizen SDK for Smartphones, Wearables and TVs

Tizen has converged all Tizen SDK for mobile, wearables, and TV to Tizen Studio since the beginning of the month, and released Tizen Studio 1.0 for developers interested in developing app for Tizen smartphones, TVs and/or smartwatches such as the latest Samsung Gear S3. So instead, you’ll now be able to select the targets platform and profiles within Tizen Studio. Some of the key changes made to the development environment in Tizen Studio 1.0 include: Launching tools: Installer, Uninstaller, and Package Manager Developing tools: IDE perspective theme, Project Wizard, Certificate Manager, and Menu and tool icons UI tools: UI Builder, Component Designer, and EDC Editor Testing tools: Emulator Testing tools: Dynamic Analyzer for memory and CPU profiling Other improvements in Tizen application development environment Tizen Studio is available for the 32-bit and 64-bit version of Windows,  and Ubuntu, as well as for Mac OS with one version with the graphics […]

Fitbit Introduces Charge 2 and Flex 2 Fitness Trackers

My first activity tracker, Vidonn X5, worked reasonably well and lasted for over a year, but the subsequent models I tried were all mostly disasters, especially as they added some features like a heart rate monitor that did not work reliably, and worse, their lifetime was poor, lasting only a few days to a few weeks before stopping working. My Xiaomi Mi Band 2 died last week-end, two days after a firmware update which decreased battery life to less than a day, and now refuses to charge. While the HRM was utterly useless, it did count steps fairly accurately, and battery life was good. Sadly, it would only last about two months. So at this stage, it might be worth spending more for a fitness tracker, and Fitbit has unveiled two new models with Charge 2 and Flex 2. Fitbit Charge 2 includes a 1.5″ OLED touchscreen display, and an […]

TW68 Smart Bracelet Measures Blood Pressure and Heart Rate for $22 and Up

Some people may need to frequently measure their blood pressure because of their health condition, but it’s often a cumbersome experience, so they may get lazy, and not do it as often as needed. TW68 smart bracelet should make this easy, as it’s your typical fitness tracker with an heart rate monitor, but adding the capability to also measure blood pressure. It’s also very cheap, and I first found it on DealExtreme where it sells for just $24. TW68 specifications: MCU – Nordic Semi NRF51822 ARM Cortex M0 micro-controller with 2.4 GHz radio Data Storage – 7 days detailed data, 23 days total data Connectivity – Bluetooth 4.0 LE Display – 0.49″ OLED display Sensors –  PixArt-PAH8001EI blood pressure sensor; 6-axis Invensense-MPU6500 accelerometer and gyroscope Function Health tracker: Blood pressure measurement, Heart rate monitor, Pedometer, Sleep tracker Other functions: Call/Message notification, Fall reminder, Social sharing, Time, Alarm clock Misc – […]
