The advancement in wireless technology and micro/nano-fabrication techniques have created a tremendous opportunity for using miniaturized wireless microelectronic devices in novel point-of-care diagnostic and prosthetic systems for a variety of health and life science applications. These new devices take advantage of miniaturized sensor technology to interface directly with complex biological structures like tissues, cells and molecules. For example, micro-electro-mechanical systems, such as microelectrode arrays and microfluidic channels, allow the study of neurons and manipulation of blood cells, while microlenses are used in low-cost fluorescence imagers. Other emerging devices, like brain machine interfaces, are opening up new opportunities to gain a better understanding of the root causes of several neuronal disorders, like the Parkinson’s disease, by extracting important biological parameters in freely moving animals. Such microsystems typically combine one or several application-specific integrated circuits with various sensor technologies into lightweight and self-contained formats that can easily be worn or implanted in the body to offer a very high level of functionality. The key requirements from such systems are: the extraction, the analysis, and the transmission of biological data in real time with excellent signal quality through a wireless connection. They are typically powered by a small battery, or by an inductive link, the power transmitter for which is external to the body, requiring extremely low power consumption to maximize the operational life expectancy.

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. Papers will be published continuously (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as 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 refereed through a 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 monthly journal published by MDPI.
The below list represents only planned manuscripts. Some of these manuscripts have not been received by the Editorial Office yet. Papers submitted to MDPI journals are subject to peer-review.
Title: An Arch-shaped Intraoral Tongue Drive System with A Built-In System-on-a-Chip Tongue-Computer Interface

We present a new arch-shaped intraoral Tongue Drive System (iTDS-A) designed to be mounted on the buccal shelf in the user's mouth. The iTDS-A system-on-a-chip (SoC) amplifies and digitizes the raw magnetic sensor data from four 3-axis magnetoresistive bridge sensors, and sends it wirelessly to an external TDS universal interface (UI) via an inductive coil or a meander antenna. A built-in transmitter (Tx) employs a dual-band radio that can operate at either 27 or 432 MHz bands, whichever offers a more robust connection, with the help of a built-in super-regenerative receiver (SR-Rx) fand the TDS-UI. An accompanying FPGA generates data packets for the built-in Tx. The iTDS-A SoC was implemented in a 0.35-µm 2P3M Std. CMOS process and on average consumes 2.8 mW and 3.3 mW at 27 MHz and 432 MHz, respectively.
