On numerical modeling of dispersive mechanical waves in lipid bi-layers [PDF]
arXiv, 2019 We investigate different mechanical effects which accompany the nerve pulse propagation by using mathematical modeling. The propagation process is composed by three connected phenomena: (i) the action potential (electrical signal) which is usually considered when nerve pulses are discussed, (ii) the mechanical wave propagating in the biomembrane and ...

Advanced Functional Materials, EarlyView.A scalable method for direct laser patterning of 2D films on transparent substrates like polycarbonate and glass is presented. This technique eliminates the need for photolithography and solvents, enabling the fabrication of functional devices like strain gauges, supercapacitors, and photodetector arrays.

On propagation failure in 1 and 2 dimensional excitable media
, 2004 We present a non-perturbative technique to study pulse dynamics in excitable media. The method is used to study propagation failure in one-dimensional and two-dimensional excitable media.

Advanced Healthcare Materials, EarlyView.In this study, a cuff‐free, less‐invasive surgical approach for vagus nerve stimulation (VNS) by combining ultrathin Y‐shaped kirigami electrodes is developed with a chemically cross‐linked hydrogel adhesive (hydrogel‐kirigami). Unlike conventional cuff implantation, which may damage nerves and nearby critical vessels, this new technique minimizes ...

Measurement of Aortic Pulse Wave Velocity With a Connected Bathroom Scale
American Journal of Hypertension, 2017 BACKGROUND Measurement of arterial stiffness should be more available. Our aim was to show that aortic pulse wave velocity can be reliably measured with a bathroom scale combining the principles of ballistocardiography (BCG) and impedance plethysmography
