Digital Signal Analysis for Abnormal Electrocardiogram (ECG) Signal Research and Development of Open Source Abnormal ECG Signal Generator

open access: yes
Digital signal processing for ECG is needed for development of ECG signal generators, mobile diagnostic devises and diagnostics in general. Most of regular signal processing methods have to be adjusted to fit ECG signal processing especially when the ECG

Ultrathin Aluminum–Air Batteries via Hygroscopic Electrolytes for Continuous Operation of Imperceptible On‐Skin Electronics

open access: yesAdvanced Energy Materials, EarlyView.
This study presents ultrathin, high‐capacity aluminum‐air batteries (AABs) for self‐sustaining, skin‐conformal electronics. By utilizing ambient moisture and oxygen alongside a LiCl‐based hygroscopic hydrogel electrolyte, the design significantly reduces battery thickness while preventing dehydration and Al self‐corrosion.
