Deep-learning-assisted thermogalvanic hydrogel fiber sensor for self-powered in-nostril respiratory monitoring.

Direct and consistent monitoring of respiratory patterns is crucial for disease prognostication. Although the wired clinical respiratory monitoring apparatus can operate accurately, the existing defects are evident, such as the indispensability of an external power supply, low mobility, poor comfort, and limited monitoring timeframes. Here, we present a self-powered in-nostril hydrogel sensor for long-term non-irritant anti-interference respiratory monitoring, which is developed from a dual-network binary-solvent thermogalvanic polyvinyl alcohol hydrogel fiber (d = 500 μm, L=30 mm) with Fe/Fe ions serving as a redox couple, which can generate a thermoelectrical signal in the nasal cavity based on the temperature difference between the exhaled gas and skin as well as avoid interference from the external environment.

Thermoelectric Hydrogel Electronic Skin for Passive Multimodal Physiological Perception.

Electronic skins (e-skins) are being extensively researched for their ability to recognize physiological data and deliver feedback via electrical signals. However, their wide range of applications is frequently restricted by the indispensableness of external power supplies and single sensory function. Here, we report a passive multimodal e-skin for real-time human health assessment based on a thermoelectric hydrogel.

Electric field and viscous fluid polarity effects on capillary-driven flow dynamics between parallel plates.

-Micropumps have attracted considerable interest in micro-electro-mechanical systems (MEMS), microfluidic devices, and biomedical engineering to transfer fluids through capillaries. However, improving the sluggish capillary-driven flow of highly viscous fluids is critical for commercializing MEMS devices, particularly in underfill applications. This study investigated the behavior of different viscous fluid flows under the influence of capillary and electric potential effects.

High-Resolution, Transparent, and Flexible Printing of Polydimethylsiloxane via Electrohydrodynamic Jet Printing for Conductive Electronic Device Applications.

In the field of soft electronics, high-resolution and transparent structures based on various flexible materials constructed via various printing techniques are gaining attention. With the support of electrical stress-induced conductive inks, the electrohydrodynamic (EHD) jet printing technique enables us to build high-resolution structures compared with conventional inkjet printing techniques. Here, EHD jet printing was used to fabricate a high-resolution, transparent, and flexible strain sensor using a polydimethylsiloxane (PDMS)/xylene elastomer, where repetitive and controllable high-resolution printed mesh structures were obtained.

Self-Powered Respiratory Monitoring Strategy Based on Adaptive Dual-Network Thermogalvanic Hydrogels.

As a low-grade sustainable heat source, the breath waste heat exhaled by human bodies is always ignored, although producing a greater temperature than ambient. Converting this heat into electric energy for use as power sources or detecting signals is extremely important in cutting-edge wearable medicine. This heat-to-electricity conversion is possible with thermogalvanic hydrogels.

A Single-Channel Wireless EEG Headset Enabled Neural Activities Analysis for Mental Healthcare Applications.

Unlabelled: Electroencephalography (EEG) is a technique of Electrophysiology used in a wide variety of scientific studies and applications. Inadequately, many commercial devices that are available and used worldwide for EEG monitoring are expensive that costs up to thousands of dollars. Over the past few years, because of advancements in technology, different cost-effective EEG recording devices have been made.

Isolated Female Epispadias with Urinary Incontinence.

Isolated female epispadias without bladder extrophy is a rare variant of female urethral anomaly reported rarely in the literature. For optimal and early management, early clinical diagnosis is important. Female with isolated epispadias usually presents with primary urinary incontinence with abnormal looking external genitalia on examination.

A Ferroelectric Ceramic/Polymer Composite-Based Capacitive Electrode Array for In Vivo Recordings.

A new implantable capacitive electrode array for electrocorticography signal recording is developed with ferroelectric ceramic/polymer composite. This ultrathin and electrically safe capacitive electrode array is capable of attaching to the biological tissue conformably. The barium titanate/polyimide (BaTiO /PI) nanocomposite with high dielectric constant is successfully synthesized and employed as the ultrathin dielectric layer of the capacitive BaTiO /PI electrode array.

A new natural gel of Fagonia indica Burm f. extract for the treatment of burn on rats.

Fagonia indica Burm f. (Mushikka or white spine) is a plant distributed in the deserts of Asia and Africa and reported to be medicinal in the scientific literature as well as in the folk medicine. Earlier investigations, the authors isolated a number of bioactive constituents from the plant including flavonoids, sterols and tritepenoids; In addition its flavonoidal content was found remarkably high reaching 3% (calculated as flavonol on dry weight).

Anti-inflammatory and gastroprotective activities of the aqueous extract of Micromeria fruticosa (L.) Druce ssp Serpyllifolia in mice.

Micromeria fruticosa is used widely in many Mediterranean regions for various inflammatory conditions. The aim of this work was to assess the anti-inflammatory and gastroprotective activities of the aqueous extract of Micromeria fruticosa. The aqueous extract of Micromeria fruticosa was tested orally in mice at doses of 50, 100 and 200 mg/kg in carrageenan-induced paw edema, vascular permeability, myeloperoxidase activity (MPO) and indomethacin-induced gastric ulceration.
