HealthyPi v4 Wearable WiFi Vital Signs Monitor Follows Raspberry Pi HAT Form Factor

HealthyPi v4 Campaign Starts ProtoCentral has started a Crowd Supply campaign for the HealthyPi v4, its latest vital signs monitoring dev kit. The HealthyPi v4 is wearable, wireless, and can be mounted on a Raspberry Pi. The units are all open source and stand-alone made for end-users, students as well as researchers and developers. An Improvement on HealthyPi v3 The recent increase in health-related tech has fueled ProtoCentral’s desire to bring its HealthyPi v3 up to current usability and development standards. The retail versions of the HealthyPi v4 are made specifically to work in conjunction with the Android OS for ease of use and mobility. Also, the Raspberry Pi HAT form factor is also supported in this version of the device. Articles On Health-Related Development The articles that have touched on health-related issues and topics from our archives, as well as very recently include HEGduino a neurofeedback monitor and […]

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 […]

Espressif ESP-Skainet Voice Assistant Offers Wake Word Engine and Speech Commands Recognition for Embedded MCUs

Skynet is finally here! OK, not quite, but at least we do have ESP-Skainet now courtesy of Espressif Systems. ESP-Skainet is an intelligent voice assistant that features the company’s WakeNet wake word engine and MultiNet speech commands recognition. WakeNet WakeNet has been specifically designed for low-power MCUs such as ESP8266 or ESP32 with a low memory footprint (20KB RAM) and a high calculation speed that makes it capable of achieving a high success rate for wake word detection even in noisy environments. Tested in the company’s upcoming LyraT-Mini audio board that combines an ESP32-WROVER-B module and a codec, WakeNet achieves a 97% wake word success rate at a one-meter distance, and 95% three meters away in a quiet environment. ESP-Skainet wake-up engine ships with the wake-up word “嗨乐鑫” (Hi Lexin), which translates in “Hello Espressif”, and supports up to five wake words. You can use customize wake words as well, […]
