The debate between all-in-one microcontrollers and modular wireless subsystems resurfaces in a compelling form when comparing Nordic Semiconductor’s nRF7002 DK and Espressif’s ESP32-based development boards. While both aim to provide developers with robust Wi-Fi-enabled prototyping platforms for embedded and IoT applications, they differ radically in architecture, power strategy, and real-world … [Read more...]

Principles of Non-Invasive Blood Glucose Measurement By Near Infrared (NIR)
Non-invasive blood glucose monitoring by NIR spectroscopy has evolved over decades as a promising alternative to finger-prick methods. However, despite significant research, regulatory approval remains elusive. Recent clinical studies, such as MDPI’s evaluation of the Glucube® NIR device involving 60 adult participants and 1,500 paired measurements, demonstrated a total MARD (Mean Absolute … [Read more...]
