“…158−160 Using the carbon material such as nanocarbon, 161,162 electronics of the future will be stretchable, twistable, and deformable into curvilinear shapes, thereby enabling applications that would be impossible to achieve by using the hard, rigid electronics of today. 163 Almost all the previous studies indicate biodegradablematerial electronics (organic bioelectronics) is current trend of the ongoing electronics revolution, proving to be the suitable host for welcoming natural and nature-inspired organic materials and a perfect trampoline for achieving the ambitious goal of "'green'" and sustainable electronics future. Despite intense effort of the scientific community during the past three decades, the performance and stability of organic semiconductors remain at current times major hurdles in their development as solid competitors of the inorganic counterparts.…”

A number of efforts have been launched to solve the global electronic waste (e-waste) problem. The efficiency of e-waste recycling is subject to variable national legislation, technical capacity, consumer participation, and even detoxification. E-waste management activities result in procedural irregularities and risk disparities across national boundaries. We review these variables to reveal opportunities for research and policy to reduce the risks from accumulating e-waste and ineffective recycling. Full regulation and consumer participation should be controlled and reinforced to improve local e-waste system. Aiming at standardizing best practice, we alter and identify modular recycling process and infrastructure in eco-industrial parks that will be expectantly effective in countries and regions to handle the similar e-waste stream. Toxicity can be deleted through material substitution and detoxification during the life cycle of electronics. Based on the idea of “Control-Alt-Delete”, four patterns of the way forward for global e-waste recycling are proposed to meet a variety of local situations.

“…For long, the major drawback of using silicon technology for applications like electronic skin has been the lack of bendability. Recent technological advances such as ultra thin chips [6,7], and the Si-NW approach [8,9], however, hold a great promise in the direction of having silicon based mechanically flexible systems.…”

This work presents fabrication and evaluation of novel POSFET (Piezoelectric Oxide Semiconductor Field Effect Transistor) devices based tactile sensing chip. In the newer version presented here, the tactile sensing chip has been fabricated using CMOS (Complementary Metal Oxide Semiconductor) technology. The chip consists of 4 x 4 POSFET touch sensing devices (or taxels) and both, the individual taxels and the array are designed to match spatiotemporal performance of the human fingertips. To detect contact events, the taxels utilize the contact forces induced change in the polarization level of piezoelectric polymer (and hence change in the induced channel current of MOS). The POSFET device on the chip have linear response in the tested dynamic contact forces range of 0.01-3 N and the sensitivity (without amplification) is 102.4 mV/N.

Wafer-scale design of lightweight and transparent electronics that wraps around hairs

Electronics on very thin substrates have shown remarkable bendability, conformability and lightness, which are important attributes for biological tissues sensing, wearable or implantable devices. Here we propose a wafer-scale process scheme to realize ultra flexible, lightweight and transparent electronics on top of a 1-mm thick parylene film that is released from the carrier substrate after the dissolution in water of a polyvinyl-alcohol layer. The thin substrate ensures extreme flexibility, which is demonstrated by transistors that continue to work when wrapped around human hairs. In parallel, the use of amorphous oxide semiconductor and high-K dielectric enables the realization of analogue amplifiers operating at 12 V and above 1 MHz. Electronics can be transferred on any object, surface and on biological tissues like human skin and plant leaves. We foresee a potential application as smart contact lenses, covered with light, transparent and flexible devices, which could serve to monitor intraocular pressure for glaucoma disease.
