Display meets biology: A vision for ubiquitous healthcare platforms

Abstract

Ever‐increasing demand for a healthy and sustainable life has been a traditional motivation behind state‐of‐the‐art medicines and precision diagnosis tools. Nowadays, the ultra‐connectivity and data‐centric initiatives that underpin the future Internet of Things is seen as another major driver of electronically enriched, highly customizable healthcare platforms. Especially, the information display technology, which already enjoys its position as an all‐round player in consumer electronics is poised to broaden its territory by envisioning a range of bio‐related features. In this review, the rising opportunities for next‐generation display‐based biotechnology and healthcare systems are critically assessed in light of recent literature. Clearly, smart combination of new materials, devices, and integration strategies has given rise to highly promising prototypes, and this article aims at highlighting some of these examples. Despite such progress, it is still unclear whether the resultant technologies will make a measurable impact in the near future, given both their own scientific limits and the lack of proper business model. In this regard, the final part of this contribution is dedicated to emergent challenges as well as development solutions that this potentially disruptive innovation may need to consider.

Frequency-triggered circuit transition in organic light-emitting diodes probed by impedance spectroscopy

“…For instance, OLEDs serve as a light source in biochemical sensors, photodynamic therapy systems, or in vivo optogenetic stimulators. [5][6][7][8][9] These platforms can be powered by energy harvesters (e.g. piezoelectric or triboelectric nanogenerators), the output of which is an ac signal.…”

Display-pixel performances driven by contact-limited switching transistors

“…Several device models have already included R c [14][15][16], yet its impact on practical circuits has received limited attention, despite the fact that a comparatively high R c requires a special emphasis in OTFT circuit design [17]. Therefore, a correct account of R c in circuit investigation is now of great importance to further extend the technological applicability of OTFT-based systems in broad target areas including displays, sensors, and wearable electronics [18].…”

OLED Opportunity in Healthcare With the Pulse Oximeter

“…Even before that, an ever‐increasing demand for healthy and sustainable life has been a traditional motivation for developing a range of precision biosensors and health monitors in service of the general public, which in most cases was realized thanks to the timely development of high‐performance electronics. Although the biotech area still seems not‐so‐directly relevant to the display industry, several advanced sensing platforms reported from academic groups suggest strong evidence that these two worlds can effectively collaborate for the common good 1 …”
