Flexible Non-contact Electrodes for Wearable Biosensors System on Electrocardiogram Monitoring in Motion

“…As the thickness of the insulating layer increases, the signal quality decreases. In theory, the further the electrode is from the source, the smaller the coupling signal ( Liu et al, 2019 ). In this experiment, we used two thicknesses of clothing for monitoring and both obtained an effective ECG signal, namely one layer and three layers.…”

Wearable sensors for monitoring vital signals in sports and health: progress and perspective

“…Subsequently, a band-pass filter was used to mitigate motion noise, resulting in the electrode demonstrating exceptional performance. This was substantiated by the acquisition of high-fidelity EMG data during the flexion or extension of the brachial muscles (Liu et al , 2019).…”

Personalized sleep aid audio strategy model based on self-attention and time-domain analysis

“…In the model, A(p) represents the comprehensive audio strategy based on the parameter set p, vj is the parameterized weight, and aj is a specific audio strategy. 10…”

“…In the model, AðpÞ represents the comprehensive audio strategy based on the parameter set p, v j is the parameterized weight, and a j is a specific audio strategy. 10 To achieve real-time audio adjustment, a dynamic parameter update strategy is required. Considering the relationship between physiological features and audio, we introduced a weight update strategy based on physiological features.…”
