Advanced Implantable, Wearable, and Bio-Integrated Antenna Systems for Next-Generation Healthcare and Wireless Applications

Dear Colleagues,

The rapid progress of bio-electromagnetics, advanced materials, artificial intelligence (AI), and next-generation wireless technologies is accelerating the development of advanced implantable, wearable, and bio-integrated antenna systems for healthcare and emerging wireless applications. These antennas serve as the electromagnetic core of modern medical devices, supporting continuous physiological monitoring, neural interfacing, targeted therapies, wireless power transfer, and intelligent closed-loop treatment systems. As healthcare shifts toward personalized, minimally invasive, and connected models, there is a growing need for compact, energy-efficient, and biologically compatible antenna solutions. In this context, AI-driven design and optimization are emerging as powerful tools to enhance antenna performance, adaptability, and system intelligence.

Establishing devices that can operate inside or on the human body presents significant challenges. Biological tissues are lossy and electromagnetically complex, leading to detuning, impedance mismatch, absorption losses, and strict safety constraints such as Specific Absorption Rate (SAR). Applications including smart prosthetics, implantable biosensors, capsule endoscopy, microwave imaging, hyperthermia-based cancer therapy, and neuromodulation require broadband or multiband functionality, mechanical flexibility, conformal geometries, and long-term stability under deformation. Machine learning and data-driven techniques are increasingly being explored to model complex tissue interactions, predict performance, and enable adaptive antenna behavior in dynamic biological environments.

Advances in high-permittivity and magneto-dielectric materials, metamaterial-inspired miniaturization, textile and stretchable conductors, additive manufacturing, 3D printing, and bioresorbable electronics are expanding design possibilities, and coupled with multiphysics modeling, realistic anatomical phantoms, and AI-driven optimization, these innovations enable safer, more efficient, and reliable systems. This Special Issue welcomes original research and comprehensive reviews addressing modeling, miniaturization, fabrication, safety-aware design, experimental validation, and system-level integration of antenna technologies for next-generation healthcare and wireless platforms, with particular emphasis on the integration of artificial intelligence and data-driven design methodologies.

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 250 words) can be sent to the Editorial Office for assessment.

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. Electronics is an international peer-reviewed open access semimonthly 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 2400 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.
