TL;DR: In this article , the authors investigated the origin of the noise in the ECG signal and found suitable solutions to reduce this disturbance, showing that the noise due to human body motions in ECG equally comes from the electrochemical equilibrium break of the reduction-oxidation reaction at the skin-electrode interface.

TL;DR: This brief introduces an innovative unidimensional thermal propagation modeling of conductor bulk structure based on the Kron–Branin (KB) formalism that is inspired from the transmission line approach by considering the bulk material thermal resistance and capacitance.
Abstract: This brief introduces an innovative unidimensional thermal propagation modeling. It consists in thermal diffusion on conductor bulk structure based on the Kron–Branin (KB) formalism. The proposed KB model is inspired from the transmission line approach by considering the bulk material thermal resistance and capacitance. The KB-based equivalent graph topology of the heated structure is elaborated. The thermal transfer function (TTF) is established from the graph analytical abstraction. The TTF enables to determine the transient and frequency-dependent temperature diffusion along the structure. The KB model effectiveness is illustrated with both frequency and time-domain analyses. Proof-of-concept constituted by copper-based bulk material is considered. The TTF from KB, finite-element-method and Cauer models are compared. With computation from dc to 100 Hz, it was shown that the frequency domain magnitude and phase are in good correction. In addition, the calculated and simulated transient heat flows along the considered structure are in good agreement by considering 120-ms duration pulse width temperature source.

TL;DR: In this paper, a microstrip 1∶4 switched power splitter (SPWS) printed on flexible Kapton substrate is designed and implemented in hybrid technology by using the packaged switch SKY13298-360LF biased with 1.8 V supply.
Abstract: A microstrip 1∶4 switched power splitter (SPWS) printed on flexible Kapton substrate is designed. The SPWS topology is designed and implemented in hybrid technology by using the packaged switch SKY13298-360LF biased with 1.8 V supply. Electromagnetic and circuit co-simulations confirm the SPWS performance to operate in the IEEE standard 802.11a bands from 5.470–5.725 GHz. The designed 1∶4 SPWS presents −3.5 dB and −30 dB insertion losses were evaluated respectively for the on- and off-state branches. Furthermore, the input and output return losses are respectively of about −17 dB and −15 dB. This flexible SPWS can be potentially used to design switched beam steering wireless system.

TL;DR: A new prototype triboelectric nanogenerator with superhydrophobic and self-cleaning features is invented to harvest water drop energy based on a sequential contact electrification and electrostatic induction process.
Abstract: A new prototype triboelectric nanogenerator with superhydrophobic and self-cleaning features is invented to harvest water drop energy based on a sequential contact electrification and electrostatic induction process. Because of the easy-fabrication, cost-effectiveness, and robust properties, the developed triboelectric nanogenerator expands the potential applications to harvesting energy from household wastewater and raindrops.
