“…Although MFC can detect bacterial electricity in a research laboratory, it requires a bacterial culture in a large chamber, making it inappropriate for operation in the home, outpatient care centers, and hospitals during teledermatology services. In recent years, small semiconductor circuits such as electronic skin patches have been widely developed to detect skin electricity attributable to changes in skin conductance and electrogenic skin bacteria [42,43]. An electronic skin patch imprints an integrated circuit with a cathode and an anode onto a thin, flexible silicon film that can be applied to the skin.…”

Teledermatology has emerged as a vital technology for remotely delivering medical care and is expected to play an adjunctive role in diagnosing skin diseases in the near future. However, a limitation of teledermatology is the current inability of the medium to assess the changes in the human skin microbiome. Skin infections or microbiome dysbiosis, particularly at early stages, cannot be promptly detected using teledermatology services. Herein, antibody-based and electron-based diagnostics are introduced as complementary tools for teledermatology to examine the infections or microbiome dysbiosis. The lateral or circular flow immunoassay methods as rapid diagnostic tests for detecting microbial antigens or antibodies were presented for patients’ self-diagnosis. The electronic skin patch was underlined as an electron-based diagnostic device for monitoring the activities of electrogenic skin microbes. Data derived from antibody-based and electron-based diagnostics can be instantly transmitted to smartphones or computers for dermatologists to track patients’ skin conditions and therapy progress.

“…Recently, whit the aim of restoring sensory feedback to amputees in closed loop application there are an increasing interest on the neuromorphic implementation of tactile sensors. The challenge is to encode the tactile information by reproducing the spiking patterns of human primary tactile afferents [71][72][73][74][75]. E-skin [71][72][73] presents a spike encoding following the slow adapting and fast adapting mechanoreceptors in human skin.…”

Bioelectronic medicine treats chronic diseases by sensing, processing, and modulating the electronic signals produced in the nervous system of the human body, labeled 'neural signals'. While electronic circuits have been used for several years in this domain, the progress in microelectronic technology is now allowing increasingly accurate and targeted solutions for therapeutic benefits. For example, it is now becoming possible to modulate signals in specific nerve fibers, hence targeting specific diseases. However, to fully exploit this approach it is crucial to understand what aspects of the nerve signals are important, what is the effect of the stimulation, and what circuit designs can best achieve the desired result. Neuromorphic electronic circuits represent a promising design style for achieving this goal: their ultra-low power characteristics and biologically plausible time constants make them the ideal candidate for building optimal interfaces to real neural processing systems, enabling real-time closed-loop interactions with the biological tissue. In this paper, we highlight the main features of neuromorphic circuits that are ideally suited for interfacing with the nervous system and show how they can be used to build closed-loop hybrid artificial and biological neural processing systems. We present examples of neural computational primitives that can be implemented for carrying out computation on the signals sensed in these closed-loop systems and discuss the way to use their outputs for neuro-stimulation. We describe examples of applications that follow this approach, highlight open challenges that need to be addressed, and propose actions required to overcome current limitations.

“…Amputations due to accidents can adversely affect a patient's quality of life, preventing them from performing the necessary movements of daily life [1][2][3]. While recent technological advancements have improved the performance of prosthetic hands and made devices increasingly flexible, the question of dexterity versus weight, form factor, and equipment cost of the prosthetic hand remains [4,5].…”

Currently, the driving motor used in a dexterous prosthetic hand is limited by the driving principle, and it has the characteristics of a complex structure, slow response, low positioning accuracy, and excessive volume. There are special requirements in terms of quality and quality, and traditional motor drives have greatly affected the progress of prosthetic robots. A motor (ultrasonic motor) has been developed over more than 30 years. It has the advantages of a small size, small mass, simple structure, accurate positioning, high power density, and fast response time, which is enough to improve the driving mechanism performance of the prosthetic hand with a connecting rod. In this paper, the structural characteristics of the prosthetic hand will be analyzed, and the modal analysis, harmonic response analysis, and transient analysis simulation of the longitudinal vibration linear motor stator used in the prosthetic hand with a connecting rod will be carried out in order to provide preliminary preparation for the feasible design and manufacture of the size of the ultrasonic driver structure used for the prosthetic hand with a connecting rod.
