Recently, B105 Electronic Systems Lab has designed and implemented a new low power electromyography (EMG) acquisition device. It could have only some milliwatts of power consumption while continuously acquiring samples from 4 channels at up to 800 Samples/s and processing them with an embedded high-end low-power microcontroller.

We are still fully testing and characterizing the device, but preliminary results are promissing and we expect to be able to reduce the power consumption to microwatts level by implementing new low power strategies in the device firmware.
