Electronic devices that are biodegradable, water soluble and flexible and are fabricated using biodegradable materials are of great importance due to their potential application in biomedical implants, personal healthcare etc. Moreover, despite the swift growth of semiconductor technologies and considering a device’s shell life of two years, the subject of electronic waste (E-waste) disposal has become a major issue. Transient electronics is a rapidly expanding field that solves the issue of E-waste by destroying the device after usage. The device disintegration can be caused by a multitude of triggering events, an example is that the device totally dissolves and/or disintegrates when submerged in water. This technology enables us to utilize electronic devices for a set amount of time before quickly destroying them, lowering E-waste significantly. This review will highlight the recent advancement in water-soluble flexible electronic devices with more focus on functional materials (water insoluble), fabrication strategies and transiency understanding with special importance on areas where these devices exhibit potential application in flexible and wearable electronic devices which includes field effect transistors, photodetectors, memristors and sensors for personal healthcare monitoring.

By virtue of energy efficiency, high speed, and parallelism, brain‐inspired neuromorphic computing is a promising technology to overcome the von Neumann bottleneck and capable of processing massive sophisticated tasks in the background of big data. The abilities of perceiving and reacting to events in artificial neuromorphic systems allow us to build the communicative electronic–biological interfaces to get closer to electronic life. Protein materials offer great application potentials in such a system due to their sustainability, low cost, controllable hierarchical structure, intrinsic biocompatibility, and biodegradability. Herein, a timely review of the development of protein‐based memories for data storage and neuromorphic computing is provided. Proteins’ unique mechanical, electronic, optical properties, and their broad applications are discussed. Then, the progress of protein‐based two‐terminal memristor and three‐terminal transistor‐type memory is reviewed, and their applications for data storage, logic circuit, and neuromorphic computing are introduced. Finally, the major challenges and outlook toward the future developing directions of protein‐based computing systems are pointed out.

“…For hybrid implantable medical device (Ma et al, 2019), one of the key concerns is their toxicity and side effects after in vivo implantation (Ruckh and Clark, 2014). Indeed, many pioneer works were reported in the past decade for the exploration of biodegradable or biocompatible materials such as silk (Song et al, 2017;Qi et al, 2019), hydrogel, and polymers, leading to minimized toxicity from the substrate of an implanted device (Mieszawska et al, 2013). Nevertheless, little attention was paid to the fate of the integrated inorganic nanosensors in the hybrid implantable devices.…”

Implantable optical sensing devices that can continuously monitor physiological temperature changes hold great potential toward applications in healthcare and medical field. Here, we present a conceptual foundation for the design of biocompatible temperature sensing device by integrating renal clearable luminescent gold nanoparticles (AuNPs) with silk film (AuNPs-SF). We found that the AuNPs display strong temperature dependence in both near-IR fluorescence intensity and lifetime over a large temperature range (10-60 • C), with a fluorescence intensity sensitivity of 1.72%/ • C and lifetime sensitivity of 0.09 µs/ • C. When integrated, the AuNPs with biocompatible silk film are implanted in the dorsal region of mice. The fluorescence imaging of the AuNPs-SF in the body shows a linear relationship between the average fluorescence intensity and temperature. More importantly, <3.68% ID gold are left in the body, and no adverse effect is observed for 8 weeks. This AuNPs-SF can be potentially used as a flexible, biocompatible, and implantable sensing device for in vivo temperature mapping.

Transient bioelectrical devices inspired by a silkworm moth breaking out of its cocoon

Abstract: Silk fibroin-based transient devices were developed using LiBr/wax microspheres that mimic a silk cocoon protecting silkworm pupa and a juvenile moth secreting an enzyme to dissolve silk sericin and break a silk cocoon.
