“…A maximal capacitance about 0.5μF/cm 2 was measured at 1.0 Hz. This obtained high capacitance is attributed to the formation of an EDL at the AZO electrode/ SA membrane interface [6]- [10] (as illustrated in the down inset of Fig. 2(b)).…”

“…The SA membrane (about 10 μm) rapidly dissolves within 5 minutes, the array hence disintegrated into individual devices and adhesive to the bottom glass. Then the thin patterned AZO layer gradually disappears as a result of the reaction ZnO + H 2 O ↔ Zn (OH) 2 [3], [10] within 60 minutes.…”

“…Figure 1 (b) shows a typical laterally coupled EDL transistor. In our recent work, we developed a novel biodegradable homo-junction EDL transistors and demonstrated that the Al:ZnO (AZO) and sodium alginate (SA) membrane are proper materials to build biodegradable transistors [10]. Figure 1 (c) shows the scheme illustration of the proposed biodegradable EDL transistors, in which the SA membrane is used simultaneously as the substrates and dielectrics for the transistors.…”

Bioresorbable Materials on the Rise: From Electronic Components and Physical Sensors to In Vivo Monitoring Systems

Over the last decade, scientists have dreamed about the development of a bioresorbable technology that exploits a new class of electrical, optical, and sensing components able to operate in physiological conditions for a prescribed time and then disappear, being made of materials that fully dissolve in vivo with biologically benign byproducts upon external stimulation. The final goal is to engineer these components into transient implantable systems that directly interact with organs, tissues, and biofluids in real‐time, retrieve clinical parameters, and provide therapeutic actions tailored to the disease and patient clinical evolution, and then biodegrade without the need for device‐retrieving surgery that may cause tissue lesion or infection. Here, the major results achieved in bioresorbable technology are critically reviewed, with a bottom‐up approach that starts from a rational analysis of dissolution chemistry and kinetics, and biocompatibility of bioresorbable materials, then moves to in vivo performance and stability of electrical and optical bioresorbable components, and eventually focuses on the integration of such components into bioresorbable systems for clinically relevant applications. Finally, the technology readiness levels (TRLs) achieved for the different bioresorbable devices and systems are assessed, hence the open challenges are analyzed and future directions for advancing the technology are envisaged.

“…The degeneracy is caused by both oxygen vacancies and substitutional tin dopants created during film deposition. [41,42] Here, leakage currents are measured with different areas of the drain electrode, as illustrated in Figure S11 (Supporting Information). To further intuitively analyze this phenomenon, the corresponding X-ray photoelectron spectrometry (XPS) spectra for different elements (O 1s, Sn 3d, and In 3d) with and without O 2 are displayed in Figure 2f and Figure S5 Figure 2f.…”

A Sub‐10 nm Vertical Organic/Inorganic Hybrid Transistor for Pain‐Perceptual and Sensitization‐Regulated Nociceptor Emulation

Pain‐perceptual nociceptors (PPN) are essential sensory neurons that recognize harmful stimuli and can empower the human body to react appropriately and perceive precisely unusual or dangerous conditions in the real world. Furthermore, the sensitization‐regulated nociceptors (SRN) can greatly assist pain‐sensitive human to reduce pain sensation by normalizing hyperexcitable central neural activity. Therefore, the implementation of PPNs and SRNs in hardware using emerging nanoscale devices can greatly improve the efficiency of bionic medical machines by giving them different sensitivities to external stimuli according to different purposes. However, current most‐normal organic/oxide transistors face a great challenge due to channel scaling, especially in the sub‐10 nm channel technology. Here, a sub‐10 nm indium‐tin‐oxide transistor with an ultrashort vertical channel as low as ≈3 nm, using sodium alginate bio‐polymer electrolyte as gate dielectric, is demonstrated. This device can emulate important characteristics of PPN such as pain threshold, memory of prior injury, and pain sensitization/desensitization. Furthermore, the most intriguing character of SRN can be achieved by tuning the channel thickness. The proposed device can open new avenues for the fascinating applications of next‐generation neuromorphic brain‐like systems, such as bio‐inspired electronic skins and humanoid robots.
