Abstract

The concept of regenerating tissues, with properties and functions that mimic natural tissues, has attracted significant attention in recent years. It provides potential solutions for treating many diseases and other healthcare issues. To fully realize the potential of the approach, it is crucial to have a rational biomaterial design to create novel scaffolds, and other materials systems suitable for tissue engineering, repair and regeneration. Research advances on the topic include the design of new biomaterials and their composites, the scaffold fabrication via subtractive and additive manufacturing approaches, the development of implantable scaffolds for disease monitoring, diagnostics, and treatment, as well as the understanding of cells–biomaterial scaffolds interaction. This Special Issue, “Novel Biomaterials for Tissue Engineering”, covers a selection of timely research activities in the field of biomaterials for tissue engineering and regeneration purposes. Promising findings on different approaches to design and develop new biomaterials, biomaterial systems and methods for tissue engineering, are presented and discussed. Recent advances in biofabrication techniques for tissue engineering are additionally demonstrated. The issue comprises a series of state-of-the-art experimental works, up-to-date review articles and commentaries.

Abstract

In this work, new concepts of body-matched antennas for microwave medical applications were developed, where the antennas are placed directly on or in the human body. Two types of antennas were designed - on-body matched antennas for diagnosis and implantable antennas for data telemetry with the main focus of miniaturization yet maintained a high radiation performance. The applicability of the antennas was verified using a medical imaging system for the detection of hemorrhagic stroke.

Abstract

Implantable microdevices, providing accurate measurement of target analytes in animals and humans, have always been important in biological science, medical diagnostics, clinical therapy, and personal healthcare. Recently, there have been increasing unmet needs for developing high-performance implants that are small, minimally-invasive, biocompatible, long-term stable, and cost-effective. Therefore, the aim of this Special Issue is to bring together state-of-the-art research and development contributions that address key challenges and topics related to implantable microdevices. Applications of primary interest include, but are not limited to, miniaturized optical sensing and imaging tools, implantable sensors for detecting biochemical species and/or metabolites, transducers for measuring biophysical quantities (e.g., pressure and/or strain), and neural prosthetic devices.

Abstract

Over the last few years Organic Semiconducting industry showed significant growth in many areas dominated by conventional electronics. The foremost advantage of organic materials is that they are cheap, lightweight and flexible. In addition, the fabrication of organic materials from a defined molecular precursor using inkjet−printing technology is simple, bypassing the need for advanced semiconductor processing techniques. Organic thin films have already found confirmed and reliable applications in flexible displays, solar cells and biomedical applications, including implantable devices. Low cost materials, compatible with current organic electronic fabrication techniques and which improve device performance are in strong demand.This special issue of Organic Semiconductors covers Materials, Fabrication Techniques, Characterization, Devices and market adoption of Organic Semiconductors.

Abstract

Soft material-enabled electronics offer distinct advantage, over conventional rigid and bulky devices, for numerous wearable and implantable applications. Soft materials allow for seamless integration with skin and tissues due to enhanced mechanical flexibility and stretchability. Wearable devices, such as sensors, offer continuous, real-time monitoring of biosignals and movements, which can be applied in rehabilitation and diagnostics, among other applications. Soft implantable electronics offer similar functionalities, but with improved compatibility with human tissues. Biodegradable soft implantable electronics are also being developed for transient monitoring, such as in the weeks following surgery. To further advance soft electronics, materials, integration strategies, and fabrication techniques are being developed. This paper reviews recent progress in these areas, toward the development of soft material-enabled electronics for medicine, healthcare, and human-machine interfaces.

Abstract

Neural electrodes enable the recording and stimulation of bioelectrical activity in the nervous system. This technology provides neuroscientists with the means to probe the functionality of neural circuitry in both health and disease. In addition, neural electrodes can deliver therapeutic stimulation for the relief of debilitating symptoms associated with neurological disorders such as Parkinson’s disease and may serve as the basis for the restoration of sensory perception through peripheral nerve and brain regions after disease or injury. Lastly, microscale neural electrodes recording signals associated with volitional movement in paralyzed individuals can be decoded for controlling external devices and prosthetic limbs or driving the stimulation of paralyzed muscles for functional movements. In spite of the promise of neural electrodes for a range of applications, chronic performance remains a goal for long-term basic science studies, as well as clinical applications. New perspectives and opportunities from fields including tissue biomechanics, materials science, and biological mechanisms of inflammation and neurodegeneration are critical to advances in neural electrode technology. This Special Issue will address the state-of-the-art knowledge and emerging opportunities for the development and demonstration of advanced neural electrodes.
