Special Issue Information

Dear Colleagues,

Modern healthcare is a vast ecosystem, and IoT/WMS-related applications have the potential to empower citizens to manage their own health and disease, using smart medical sensors, remote monitoring, smartphone-enabled data aggregation, medical AI and analysis, and context-aware assistive living technologies. The necessity for remote monitoring today has never been greater, even more evident during the COVID-19 pandemic, and there is an eminent demand for the expansion of new modes of healthcare delivery. Today, there is not an out-of-the-box solution combining synchronous unobtrusive ubiquitous in-transit persistent information capture, analysis (i.e., AI), aggregation, storage, and transfer within modern monitoring environments able to overcome network instabilities and incompatibilities. There is a need to research underlying architectures for WMS and services, embracing the transmission and interpretation of different biosignals from fixed or mobile locations, multi-purpose heterogeneous networking infrastructures, and AI as means for developing smart processing for medical diagnosis and treatment, data harmonization and sharing, linking data services and devices, filling in missing information, and enabling secure and explainable wireless healthcare sensing services. This issue focuses on research related to smart wireless medical sensors and how beyond SoA solutions can infiltrate and disrupt healthcare spaces.

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. Sensors 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 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.

Wireless passive neural recording systems integrate sensory electrophysiological interfaces with a backscattering-based telemetry system. Despite the circuit simplicity and miniaturization with this topology, the high electrode–tissue impedance creates a major barrier to achieving high signal sensitivity and low telemetry power. In this paper, buffered impedance is utilized to address this limitation. The resulting passive telemetry-based wireless neural recording is implemented with thin flexible packages. Thus, the paper reports neural recording implants and integrator systems with three improved features: (1) passive high impedance matching with a simple buffer circuit, (2) a bypass capacitor to route the high frequency and improve mixer performance, and (3) system packaging with an integrated, flexible, biocompatible patch to capture the neural signal. The patch consists of a U-slot dual-band patch antenna that receives the transmitted power from the interrogator and backscatters the modulated carrier power at a different frequency. When the incoming power was 5–10 dBm, the neurosensor could communicate with the interrogator at a maximum distance of 5 cm. A biosignal as low as 80 µV peak was detected at the receiver.
