الوصف: Mechanoreceptors endow humans with the sense of touch by translating the external stimuli into coded spikes, inspiring the rise of artificial mechanoreceptor systems. However, to incorporate slow adaptive receptors-like pressure sensors with artificial neurons remains a challenge. Here we demonstrate an artificial mechanoreceptor by rationally integrating a polypyrrole-based resistive pressure sensor with a volatile NbOx memristor, to mimic the tactile sensation and perception in natural skin, respectively. The artificial mechanoreceptor enables the tactile sensory coding by converting the external mechanical stimuli into strength-modulated electrical spikes. Also, tactile sensation enhancement is achieved by processing the spike frequency characteristics with the pulse coupled neural network. Furthermore, the artificial mechanoreceptor can integrate signals from parallel sensor channels and encode them into unified electrical spikes, resembling the coding of intensity in tactile neural processing. These results provide simple and efficient strategies for constructing future bio-inspired electronic systems.

The presented confocal microscope head is composed of (1) an optical fiber bundle, (2) a custom-designed mechanical housing and lastly, (3) an embedded electronic system to control the head and gather images from the samples. The dimensions of the housing are 88 × 160 × 110 mm; and it is 3D printed with 30% filling ratio using standard PLA 3D printing material. The presented handheld confocal microscope is capable of moving with 1 µm step size back and forth in axial direction and has a dynamic range of 2 cm. The results show that cost-effective 3D printing methods are suitable for realizing a handheld confocal microscope with an axial movement feature. Using cheap and replaceable 3D printed parts can ease the cleaning and disinfection procedures in clinical practices.

الوصف: The aim of the present study was to compare in terms of pain perception the use of conventional anesthesia and a computerized system. Forty patients in need for extractions, dental restorative, or periodontal treatment bilaterally, were selected. Each patient served as his/her own control being subjected to two anesthesia techniques: conventional and electronically controlled anesthesia with Calaject® (Ronvig Dental MFG, Daugaard, Denmark). Each patient received both treatments in a blind way 1 week apart. The order was previously randomized. After performing the anesthesia (upper dental nerve, palatal posterior nerve, or inferior alveolar nerve), the patients evaluated their pain sensation with a visual analogue scale (VAS) (0–10). After treatment, the patients were asked about the presence of pain during the procedure. Finally, the patients selected their preference between the conventional and electronic anesthesia technique. Differences in assessment of pain’s injection were analyzed using the Wilcoxon test and the Kruskal-Wallis test (α = 0.05). The mean general pain experienced was 3.73 (1.55 SD) for the conventional anesthesia, and 1.95 (0.53 SD) for computerized anesthesia. Statistical differences (p

الوصف: Since Moore’s law in the traditional semiconductor industry is facing shocks, More Moore and More than Moore are proposed as two paths to maintain the development of the semiconductor industry by adopting new architectures or new materials, in which the former is committed to the continued scaling of transistors for performance enhancement, and the latter pursues the realization of functional diversification of electronic systems. Two-dimensional (2D) materials are supposed to play an important role in these two paths. In More Moore, the ultimate thin thickness and the dangling-bond-free surface of 2D channels offer excellent gate electrostatics while avoiding the degradation of carrier mobility at the same time, so that the transistors can be further scaled down for higher performance. In More than Moore, devices based on 2D materials can well meet the requirements of electronic systems for functional diversity, like that they can operate at high frequency, exhibit excellent sensitivity to the changes in the surroundings at room temperature, have good mechanical flexibility, and so on. In this review, we present the application of 2D materials in More Moore and More than Moore domains of electronics, outlining their potential as a technological option for logic electronics, memory electronics, radio-frequency electronics, sensing electronics, and flexible electronics.
