Implantable Flexible Electronics: Materials and Techniques for Implantable Nutrient Sensing Using Flexible Sensors Integrated with Metal–Organic Frameworks (Adv. Mater. 23/2018)

Abstract

The combination of metal‐organic frameworks (MOFs) and flexible electronics to yield a distributed biosensor is demonstrated by Hang Xu, and Xian Huang, and co‐workers in article number https://doi.org/10.1002/adma.201800917. A multichannel flexible device is integrated with nanosized MOFs to conduct highly specific electrochemical sensing of nutrients. Techniques and materials are revealed to monitor the distribution and transportation of nutrients and other biomolecules in multiple organ locations with high throughput, offering promising tools for understanding the mechanisms of symptoms related to nutrient deficiency, metabolism disorder, and neurological disease.

Metal–organic framework-based platforms for implantation applications: recent advances and challenges

“…6a). 87 Then, they were dropwise injected into the working electrode obtained through screen printing to achieve surface functionalization modification. Through the oxidation of metal nodes in the selected MOFs materials, specific recognition and detection of nutrients such as ascorbic acid, L-tryptophan, glycine, and glucose are achieved, thereby monitoring human metabolism and circulation processes.…”

In situ SEM observation and interface adhesion strength analysis of a serpentine interconnect on a flexible electronic composite film

“…lexible electronic composite films composed of a serpentine metal interconnect and a flexible substrate are widely used in artificial electronic skin, 1,2) implantable bioelectronics, 3,4) flexible solar cells 5,6) and other products. The interface structure of a flexible electronic composite film determines its interface behavior and mechanical properties.…”

Design and Assembly of Reconfigurable 3D Radio‐Frequency Antennas Based on Mechanically Triggered Switches

“…For decades, several different types of reconfigurable antennas have been designed and fabricated, but most of them are limited either by the tunable range of frequency or by the mechanical deformability (e.g., flexibility/stretchability required in biointegrated devices, such as wearable/implantable electronics). For example, some works rely on a variety of switches (including, PIN diodes, optoelectronic switches, and micro‐electromechanical systems (MEMS) switches) to control the resonant frequency of the antennas by changing the length of the radiating elements.…”
