Special Issue Information

Dear Colleagues, 

With the upcoming Internet of Things (IoT) era, people want to receive and exchange more information using the state-of-the-art smart devices in their daily lives. Among the various electronic devices available, wearable smart devices have found themselves in the spotlight as a powerful infocommunication tool for new human–machine and human–human interface. Flexible/wearable electronics have been proposed as a key technology for bilateral communication in a hyperconnected society, due to their light weight, high accessibility, and excellent portability. With the extension of the wearable/flexible electronics field, several researchers have developed such technologies. However, various factors have to be taken into account for the enhancement of device performance in terms of device structure, materials, and fabrication processes. Enhanced wearable/flexible electronic devices can be utilized for various applications, such as health monitoring sensors, healthcare devices, displays, large-scale integrations (LSI), and so on. This Special Issue focuses on the design, materials, fabrication process, and applications for flexible and wearable electronic devices. 

The topics of interest include but are not limited to:

  • New device architecture;
  • Materials for flexible/wearable electronics;
  • MEMS/NEMS for flexible/wearable electronics;
  • Novel technology for flexible/wearable electronics (e.g., nanoparticles, nanowires, and laser interaction);
  • Flexible/wearable power electronics;
  • Flexible/wearable optoelectronics;
  • Device integration in flexible/wearable electronics;
  • Bioapplications using flexible/wearable electronics (e.g., health monitoring sensors and healthcare devices).

The fabrication of underwater devices is necessary for the exploration of water environments and interactions in the Human–Computer Interaction (HCI) field. However, there are fewer approaches to support prototyping used in water environments. The existing prototype methods lack systematic waterproof treatments and provide insufficient software for balance and buoyancy analysis. To address these limitations, we present ElectroPaper, a new approach for the design and fabrication of prototypes used in water environments (surface or beneath) with paper-based electronic interfaces with a crease layer, hardware distribution layer, and hollow-out layer to support physical properties, such as waterproofing, foldability, and conformability. The approach includes a computational design tool for assisting in balance analysis, three-dimensional (3D) model unfolding, and circuit drawing. We describe the design and fabrication process and provide several example applications to illustrate the feasibility and utility of our approach. ElectroPaper provides an inexpensive and effective medium for the fabrication of customized digital prototypes for water environment use. Full article

In this paper, we briefly reviewed the development of cranial windows and their functions in brain sciences. We demonstrated that a 3D-printed titanium frame coated with a polydimethylsiloxane (PDMS) film could serve as an excellent transparent cranial window for long-period, in vivo optical experiments in mice and rats, and the devices also allowed multiple injections through the elastic PDMS window, without leaking. Our large-area honeycomb structured Ti-PDMS samples had a relative transparent area ratio of over 90% but a mechanical strength close to that of a human skull, showing a promising potential for applications in large animals as multifunctional cranial windows. We also suggested that more functional modules could be integrated in the large-area Ti-PDMS cranial device, thus turning it into a novel wearable smart platform for wireless data communication, electro-probing and brain stimulation, optical imaging, transcranial injection, and so on, for both fundamental research on neuroscience and clinical practices dealing with brain damage and disease.

Optical health monitoring and treatment have been spotlighted due to their biocompatible properties. Several researchers are investigating optical devices for obtaining health signals and curing diseases without any damage to the body. In particular, μLEDs have received a lot of attention as a future light source due to their superior optical/electrical properties, environmental stability, and structural advantages. According to their strengths, μLEDs have been used for various biomedical applications, such as optogenetics and hair regrowth. In this paper, we introduce the research tendency of μLEDs and the latest bio-applications. Full article
