Special Issue Information

Dear Colleagues,

Over the past decade, soft, deformable electronics have attracted a great deal of attention. Many researchers have fabricated flexible/stretchable displays and tactile sensors for use in electronics to generate buckled structures, and elastic conductive composites have been printed for use in energy storage.

 Sensors with excellent flexibility and stretchability are crucial components that can provide health monitoring systems with the capability to continuously track various signals including wrist pulse, heart rate, and blood glucose, without conspicuous uncomfortableness and invasiveness. Therefore, considerable effort has been made to design more conforming, miniaturized, and skin-attachable health monitoring sensors. Controlling the nano-/micro-scale morphologies of organic, inorganic, and hybrid materials can allow for the development of characteristics such as high flexibility. However, the development of skin-attachable and monolithic healthcare devices composed of flexible and multifunctional sensors, stretchable interconnections, wireless communication systems, and sustainable power sources still poses a significant challenge. 

 Potential topics include but are not limited to the following:

  • Stretchable/flexible sensors;
  • Functional/stretchable polymer materials with applications in sensor technology;
  • MEMS/NEMS for flexible/stretchable sensors;
  • Signal transmission or wireless systems for flexible/stretchable sensors;
  • Machine learning for polymer-based electronics;
  • Healthcare monitoring and diagnosis applications of sensors;
  • Review articles on the current properties and applications of polymer-based sensors.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

As an alternative to conventional 3D printing methods that require supports, a new 3D printing strategy that utilizes guided light in situ has been developed for fabricating freestanding overhanging structures without supports. Light intensity has been found to be a crucial factor in modifying the dimensions of structures printed using this method; however, the underlying mechanism has not been clearly identified. Therefore, the light-intensity-dependent changes in the structure dimensions were analyzed in this study to elucidate the associated mechanism. Essentially, the entire process of deposition was monitored by assessing the behavior of photocurable droplets prior to their collision with the structure using imaging analysis tools such as a high-speed camera and MATLAB®. With increasing light intensity, the instability of the ejected falling droplets increased, and the droplet directionality deteriorated. This increased the dispersion of the droplet midpoints, which caused the average midpoints of the deposited single layers to shift further away from the center of the structure. Consequently, the diameter of the structure formed by successive stacking of single layers increased, and the layer thickness per droplet decreased. These led to light-intensity-dependent differences in the diameter and height of structures that were created from the same number of droplets. Full article
