Peristaltic Waves as Optimal Gaits in Metameric Bio-Inspired Robots

Frontiers in Robotics and AI, 2018
Peristalsis, i.e., a motion pattern arising from the propagation of muscle contraction and expansion waves along the body, is a common locomotion strategy for limbless animals.

The Vibrio type VI secretion system induces intestinal macrophage redistribution and enhanced intestinal motility

mBio
Intestinal microbes, whether resident or transient, influence the physiology of their hosts, altering both the chemical and the physical characteristics of the gut. An example of the latter is the human pathogen Vibrio cholerae’s ability to induce strong

Ingestive behaviour and physiology of the medicinal leech [PDF]

, 1988
Ingestion lasts 25 min in Hirudo medicinalis and is characterized by pharyngeal peristalsis which fills the crop. This peristalsis has an initial rate of 2.4 Hz which decays smoothly to 1.2 Hz at termination of ingestion. During ingestion, the leech body

Utilization of modified Darcy's law in peristalsis with a compliant channel: applications to thermal science

, 2020
This research addresses the combined influence of MHD and slip on the peristaltic flow of non-Newtonian Sisko fluid model in a symmetric compliant characteristic channel. The fluid under investigation fills the porous space in a channel.

Soft Ionic and Electronic Triboelectric Nanogenerators: Toward Attachable and Implantable Biomedical Applications

Advanced Materials, EarlyView.
This review provides an overview of triboelectric nanogenerator (TENG)–based biomedical applications by classifying studies into electronic and ionic systems across attachable and implantable platforms. It summarizes key material choices, device structures, and working mechanisms that characterize current TENG‐based research, and outlines six future ...
