The world is full of connected devices – and more are coming. In 2017, there were an estimated 8.4 billion internet-enabled thermostats, cameras, streetlights and other electronics. By 2020 that number could exceed 20 billion, and by 2030 there could be 500 billion or more. Because they’ll all be online all the time, each of those devices – whether a voice-recognition personal assistant or a pay-by-phone parking meter or a temperature sensor deep in an industrial robot – will be vulnerable to a cyberattack and could even be part of one.

Today, many “smart” internet-connected devices are made by large companies with well-known brand names, like Google, Apple, Microsoft and Samsung, which have both the technological systems and the marketing incentive to fix any security problems quickly. But that’s not the case in the increasingly crowded world of smaller internet-enabled devices, like light bulbs, doorbells and even packages shipped by UPS. Those devices – and their digital “brains” – are typically made by unknown companies, many in developing countries, without the funds or ability – or the brand-recognition need – to incorporate strong security features.

Submission Deadline: December 26, 2017

The Journal of The Electrochemical Society Focus Issue on Ubiquitous Sensors and Systems for IoT is currently accepting manuscripts.

Ubiquitous sensors are becoming an integral part of Internet of Things (IoT) applications, and progress in this domain can be seen each month. The promise is that everyone and everything will be connected via wireless data collection, and services like healthcare will be brought to everyone, everywhere, anytime, for virtually any need.

These devices sense the environment and provide applications in home automation, home safety and comfort, and personal health. At a macro level they provide data for smart cities, smart agriculture, water conservation, energy efficiency industry 4.0, and Society 5.0.

Other applications include supply chain management, transportation, and logistics.

The consumer demand for seamless, integrated technology is on the rise, and with it grows the Internet of Things, which is expected to grow to a multitrillion-dollar market by 2020. But in order to develop a fully integrated electronic network, flexible, lightweight, rechargeable power sources will be required.

A team of researchers from Ulsan National Institute of Science and Technology is looking to address that issue, developing inkjet-printed batteries that can be modified to fit devices of any shape and size. The team reports that the newly developed inks can be printed onto paper to create a new class of printed supercapacitors.

This from Ulsan National Institute of Science and Technology:

The process involves using a conventional inkjet printer to print a preparatory coating—a ‘wood cellulose-based nanomat’—onto a normal piece of A4 paper. Next, an ink of activated carbon and single-walled nanotubes is printed onto the nanomat, followed by an ink made of silver nanowires in water. These two inks form the electrodes. Finally, an electrolyte ink—formed of an ionic liquid mixed with a polymer that changes its properties when exposed to ultraviolet light—is printed on top of the electrodes. The inks are exposed at various stages to ultraviolet irradiation and finally the whole assembly is sealed onto the piece of paper with an adhesive film.

Sensors detect and measure changes in position, temperature, light, etc. and they are necessary to turn billions of objects into data-generating “things” that can report on their status, and in some cases, interact with their environment.

With countless companies adopting the ever growing technology that is the Internet of Things (IoT), it is expected to grow to a multitrillion-dollar market by the year 2020.

The basic concept of IoT is to bring as many things into the digital fold as possible and create an ultimate sense of interconnection through hardware and software – but most importantly, through sensors.
