Energy and Performance Analysis of Lossless Compression Algorithms for Wireless EMG Sensors

open access: yesSensors, 2021
Electromyography (EMG) sensors produce a stream of data at rates that can easily saturate a low-energy wireless link such as Bluetooth Low Energy (BLE), especially if more than a few EMG channels are being transmitted simultaneously. Compressing data can
