Special Issue Information

Dear Colleagues,

Recent advances in soft materials, miniaturization of wireless electronics, optoelectronics, and energy harvesting strategies have enabled new classes of implantable devices that match the mechanical properties of their biological hosts. Such properties have paved the way for new approaches in the creation of biointerfaces, sensors, therapeutic devices, and research tools to analyze and manipulate biological systems. To realize the full potential of these new device classes, advancements in energy harvesting, low-power wireless electronics, sensing strategies, drug delivery, closed-loop regulation, chronic encapsulation strategies, cellular-scale light sources and detectors, as well as chronically stable tissue interfaces will elevate our capabilities and ultimately result in next-generation precision telemedicine tools with broad impact on the medical community. With this Special Issue, we aim to present the progress in the field of implantable devices and highlight promising avenues to scalable solutions that could achieve lifetimes that allow applications in human subjects. In addition to the dissemination of original works in the form of full papers and short communications, emerging and established leaders in the field are also invited to contribute commentaries, perspectives, and insightful reviews.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Micromachines is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Gastrointestinal (GI) electrical stimulation has been shown in several studies to be a potential treatment option for GI motility disorders. Despite the promising preliminary research progress, however, its clinical applicability and usability are still unknown and limited due to the lack of a miniaturized versatile implantable stimulator supporting the investigation of effective stimulation patterns for facilitating GI dysmotility. In this paper, we present a wireless implantable GI modulation system to fill this technology gap. The system consists of a wireless extraluminal gastrointestinal modulation device (EGMD) performing GI electrical stimulation, and a rendezvous device (RD) and a custom-made graphical user interface (GUI) outside the body to wirelessly power and configure the EGMD to provide the desired stimuli for modulating GI smooth muscle activities. The system prototype was validated in bench-top and in vivo tests. The GI modulation system demonstrated its potential for facilitating intestinal transit in the preliminary in vivo chronic study using porcine models. Full article
