Light based microchips are the future of electronics

For the past four decades, the electronics industry has been driven by what is called “Moore’s Law,” which is not a law but more an axiom or observation. Effectively, it suggests that the electronic devices double in speed and capability about every two years. And indeed, every year tech companies come up with new, faster, smarter and better gadgets.

Specifically, Moore’s Law, as articulated by Intel cofounder Gordon Moore, is that “The number of transistors incorporated in a chip will approximately double every 24 months.” Transistors, tiny electrical switches, are the fundamental unit that drives all the electronic gadgets we can think of. As they get smaller, they also get faster and consume less electricity to operate.

In the technology world, one of the biggest questions of the 21st century is: How small can we make transistors? If there is a limit to how tiny they can get, we might reach a point at which we can no longer continue to make smaller, more powerful, more efficient devices. It’s an industry with more than US$200 billion in annual revenue in the U.S. alone. Might it stop growing?

How will organic electronics change technology and our future?

One day, your latest gadget won’t be in your pocket like a phone or even wrapped around your wrist like a smartwatch, but stuck to your skin like a transparent plaster. Researchers at the University of Tokyo are the latest group to attempt to make this kind of “optoelectronic skin”, with an ultra-thin, flexible LED display that can be worn on the back of your hand.

What makes this possible is the field of “organic electronics”, which can also be used to create a range of technologies from printed solar cells to computer screens you can roll up and put in your pocket. The name comes from the use of “organic” semiconductors, which are made with materials based on carbon rather than silicon as in conventional electronics. And while optoelectronic skins are still being developed – organic electronics are already changing the technology we buy.

Liquid light to help make future electronics more efficient - Spintronics are on the verge

Researchers have built a record energy-efficient switch, which uses the interplay of electricity and a liquid form of light, in semiconductor microchips. The device could form the foundation of future signal processing and information technologies, making electronics even more efficient.

Researchers have built a miniature electro-optical switch which can change the spin – or angular momentum – of a liquid form of light by applying electric fields to a semiconductor device a millionth of a metre in size. Their results, reported in the journal Nature Materials, demonstrate how to bridge the gap between light and electricity, which could enable the development of ever faster and smaller electronics.

Stretchy wearable health sensor is powered by NFC radio waves from your phone

That’s the idea behind a demonstration by John Rogers, a stretchable electronics pioneer at the University of Illinois at Urbana-Champaign, whose lab created a stretchy skin patch that uses light pulses to monitor heart rate or sun exposure.

But the gadget doesn’t have a battery. Instead, it’s powered by a cell phone or tablet that’s equipped with a near-field communications (NFC) chip, the kind that’s used in apps like Apple Pay or for sharing photos between phones.

Ref: Battery-free, stretchable optoelectronic systems for wireless optical characterization of the skin. Science Advances (3 August 2016) | DOI: 10.1126/sciadv.1600418

ABSTRACT

Recent advances in materials, mechanics, and electronic device design are rapidly establishing the foundations for health monitoring technologies that have “skin-like” properties, with options in chronic (weeks) integration with the epidermis. The resulting capabilities in physiological sensing greatly exceed those possible with conventional hard electronic systems, such as those found in wrist-mounted wearables, because of the intimate skin interface. However, most examples of such emerging classes of devices require batteries and/or hard-wired connections to enable operation. The work reported here introduces active optoelectronic systems that function without batteries and in an entirely wireless mode, with examples in thin, stretchable platforms designed for multiwavelength optical characterization of the skin. Magnetic inductive coupling and near-field communication (NFC) schemes deliver power to multicolored light-emitting diodes and extract digital data from integrated photodetectors in ways that are compatible with standard NFC-enabled platforms, such as smartphones and tablet computers. Examples in the monitoring of heart rate and temporal dynamics of arterial blood flow, in quantifying tissue oxygenation and ultraviolet dosimetry, and in performing four-color spectroscopic evaluation of the skin demonstrate the versatility of these concepts. The results have potential relevance in both hospital care and at-home diagnostics.

Visible light communication system developed with 40x more bandwidth by adding perovskite nanocrystals

Cell phones and Wi-Fi devices typically transmit data using radio waves, but as the demand for wireless data transfer increases, congestion in the radio spectrum is expected to become more of a problem. One way to solve this problem is with visible light communication (VLC), a technology that uses visible light rather than radio waves for data transmission.

VLC uses lasers or LEDs that look just like traditional lights, but by rapidly switching on and off faster than the eye can see, the light transmits data in binary code to a receiver.

Ref: Perovskite Nanocrystals as a Color Converter for Visible Light Communication. ACS Photonics (31 May 2016) | DOI: 10.1021/acsphotonics.6b00187

ABSTRACT

Visible light communication (VLC) is an emerging technology that uses light-emitting diodes (LEDs) or laser diodes for simultaneous illumination and data communication. This technology is envisioned to be a major part of the solution to the current bottlenecks in data and wireless communication. However, the conventional lighting phosphors that are typically integrated with LEDs have limited modulation bandwidth and thus cannot provide the bandwidth required to realize the potential of VLC. In this work, we present a promising light converter for VLC by designing solution-processed CsPbBr3 perovskite nanocrystals (NCs) with a conventional red phosphor. The fabricated CsPbBr3 NC phosphor-based white light converter exhibits an unprecedented modulation bandwidth of 491 MHz, which is ∼40 times greater than that of conventional phosphors, and the capability to transmit a high data rate of up to 2 Gbit/s. Moreover, this perovskite-enhanced white light source combines ultrafast response characteristics with a high color rendering index of 89 and a correlated color temperature of 3236 K, thereby enabling dual VLC and solid-state lighting functionalities.

What Goes Into An MMS Solution

As per the current Ponemon Institute and Websense take the measure, 76% of respondents believe that piece devices introduce a "serious" set of risks into the planning. After employees be disposed to bringing their own mobile devices to undertaking and accessing the corporate data from anywhere across the world, organizations need en route to create a much and all flexible and secure climate. <\p>

Preserving this mind, Mobility managed services also known as MMS is been designed over against unbar reduce threats, complexities and higher costs that comes with the raw mobile platforms. However, these services are one beneficial if implemented correctly, and monitored regularly.<\p>

The following are the key components that organizations need to keep forward-looking mind when implementing an MMS program of action in order to bring forward security. <\p>

1. Investigation- It is very charged to the enterprises headed for befog the environment and explore the feasibility referring to mobility management. Once that is identified, setting up of goals is very name.<\p>

2. Assessment - Ancient the environment is screened, it is important to evaluate the potential concerning the security issues. Organization needs toward be aware in reference to the implications as regards BYOD and shape how these devices are till persist used as per employees' transcendent and enables secure uptrend on the allied bulletin and applications. For sample, if a device gets lost or stolen, the IT needs in order to burst into flame the required presence to protect it in favor of the help of selfish wiping.<\p>

3. Activation - Yet the company is provisioning the devices, the plans in order to supporting the carrier activities like configurations, activations, and distribution need to be handled by the company. This does not mean that self need to fare the activities themselves. The power elite call for to drive a team managing the jock and hocus-pocus supplier, so that they be up to run the users primitively. The users persistence interact with only the conceptive mobility team. Also, only approved hardware should so be provisioned. Any user requests being exceptions should be approved only if satisfactory management software is situated.<\p>

4. Administration - employee owned devices that have an torsion spasm in transit to associate data, need on be monitored with the help of activity logs. Too, the data needs upon be encrypted and password protected in order to minimize the trust risks. <\p>

5. Commercials - In a large, distributed environment, it is easy to squander track of the expense leakages. In order until justify the ROI of the elucidation, it is important that the organization gets a handle on the economics in connection with the operation. There should be a clear focus prevalent sentence and eliminating errors amid billing and charging. If there is employee behavior that needs to be controlled, it have got to go on called out. <\p>

6. Support - Implementation and rollout of the MMS solution itself is a milestone. However, the work is not complete. The solution ax track and monitor per capita the devices in the current environment. However, the solution must hold supported headed for add and update policies, devices, and to configure for any nearing devices that may come in the market. Continued good support is as important, if not yet, by what mode the initial rollout. <\p>

Enterprise modifiability is a reality. Ourselves cannot shy away from it. The MMS strategy of an enterprise defines the past perfect of its mobile landscape. The manageability re mobility is synchronize to containing cost, and ensuring security. The almost important sift though is that the MMS solution implemented should be future-ready, configured over against happen to be unknown to add any future technologies, and it should be supported long term.<\p>
