Special Issue Information

Dear Colleagues,

Physiological electrical signals can directly reflect people's physical conditions and play an important role in disease diagnosis and treatment. With the emergence of various portable devices and wearable devices, the collection of physiological electrical signals has received increasing amounts of attention. In recent years, as many researchers have devoted themselves to the research of physiological electrical signal collection electrodes, microneedle array dry electrodes based on Micro Electro Mechanical Systems (MEMSs) technology have gradually matured. Microneedle array dry electrodes penetrate human skin through microneedles to achieve the continuous, long-term, and efficient collection of physiological electrical signals. Due to their low cost, simple operation, no discomfort to the subject, and high collection quality, they have gradually replaced traditional wet electrodes, thus providing an effective solution for surface biopotential recording in a safe and efficient way.

With the development of materials science, electronics, biomedical engineering, and other related fields, the development of microneedle array electrodes in the biomedical field has been accelerated. This Special Issue of Biosensors, titled “Recent Advances in Microneedle Array Electrodes in Biomedicine”, will focus on various aspects of research and development related to this field.

There is great interest in the development of prosthetic limbs capable of complex activities that are wirelessly connected to the patient’s neural system. Although some progress has been achieved in this area, one of the main problems encountered is the selective acquisition of nerve impulses and the closing of the automation loop through the selective stimulation of the sensitive branches of the patient. Large-scale research and development have achieved so-called “cuff electrodes”; however, they present a big disadvantage: they are not selective. In this article, we present the progress made in the development of an implantable system of plug neural microelectrodes that relate to the biological nerve tissue and can be used for the selective acquisition of neuronal signals and for the stimulation of specific nerve fascicles. The developed plug electrodes are also advantageous due to their small thickness, as they do not trigger nerve inflammation. In addition, the results of the conducted tests on a sous scrofa subject are presented. Full article
