Electronic Skin Bridges The Gap Between You and Iron Man

Human skin contains sensitive nerve cells that detect pressure, temperature and other sensations that allow tactile interactions with the environment. To help robots and prosthetic devices attain these abilities, scientists are trying to develop electronic skins.

Now researchers report a new method in ACS Applied Materials and Interfaces that creates an ultrathin, stretchable electronic skin, which could be used for a variety of human-machine interactions. See a video of the e-skin here.

Electronic skin could be used for many applications, including prosthetic devices, wearable health monitors, robotics and virtual reality. A major challenge is transferring ultrathin electrical circuits onto complex 3D surfaces and then having the electronics be bendable and stretchable enough to allow movement.

Some scientists have developed flexible “electronic tattoos” for this purpose, but their production is typically slow, expensive and requires clean-room fabrication methods such as photolithography. Mahmoud Tavakoli, Carmel Majidi and colleagues wanted to develop a fast, simple and inexpensive method for producing thin-film circuits with integrated microelectronics.

In the new approach, the researchers patterned a circuit template onto a sheet of transfer tattoo paper with an ordinary desktop laser printer. They then coated the template with silver paste, which adhered only to the printed toner ink. On top of the silver paste, the team deposited a gallium-indium liquid metal alloy


U.S. Government Seeks Skynet As DARPA Announces $2B Artificial Intelligence Challenge

The Defense Advanced Research Projects Agency, DARPA, has announced a $2 Billion Dollar Challenge to companies and universities for the development of the next generation of artificial intelligence computer systems with military applications, akin to the Terminator movie series’ Skynet and the Terminators themselves.

The text of the DARPA’s full announcement appears below. Before reading it, the Sentinel suggests two things to keep in mind:

1. Despite the benign objectives listed in then proposal, DARPA has, not once in 60 years, spent any kind of money on projects whose purpose is to stream line administrative procedures, such as the release suggests “key areas to be explored may include automating critical DoD business processes, such as security clearance vetting in a week or accrediting software systems in one day for operational deployment…” DARPA’s projects are intended to help us get them before they get us. Third generation AI when developed, will be used for that purpose, and $2,000,000,000.00 is intended to see that it can, not to take human delays out of background screening.


2. As much as our military having Skynet and Terminators might strike fear in a Citizen’s heart, the idea of any other nation developing them first is a terror too vast to contemplate.

If someone is to develop them, and they will be developed, best we do it before some militant dictator or suppressive regime does.  The future of our liberty may depend on it.


DARPA Announces $2 Billion Campaign to Develop Next Wave of AI Technologies

DARPA’s multi-year strategy seeks contextual reasoning in AI systems to create more trusting, collaborative partnerships between humans and machines


Over its 60-year history, DARPA has played a leading role in the creation and advancement of artificial intelligence (AI) technologies that have produced game-changing capabilities for the Department of Defense. Starting in the 1960s, DARPA research shaped the first wave of AI technologies, which focused on handcrafted knowledge, or rule-based systems capable of narrowly defined tasks. While a critical step forward for the field, these systems were fragile and limited. Starting in the 1990s, DARPA helped usher in a second wave of AI machine learning technologies that created statistical pattern recognizers from large amounts of data. The agency’s funding of natural language understanding, problem solving, navigation and perception technologies has led to the creation of self-driving cars, personal assistants, and near-natural prosthetics, in addition to a myriad of critical and valuable military and commercial applications. However, these second wave AI technologies are dependent on large amounts of high quality training data, do not adapt to changing conditions, offer limited performance guarantees, and are unable to provide users with explanations of their results.

To address the limitations of these first and second wave AI technologies, DARPA seeks to explore new theories and applications that could make it possible for machines to adapt to changing situations. DARPA sees this next generation of AI as a third wave of technological advance, one of contextual adaptation. To better define a path forward, DARPA is announcing today a multi-year investment of more than $2 billion in new and existing programs called the “AI Next” campaign. Agency director, Dr. Steven Walker, officially unveiled the large-scale effort during closing remarks today at DARPA’s D60 Symposium taking place Wednesday through Friday at the Gaylord Resort and Convention Center in National Harbor, Maryland.

“With AI Next, we are making multiple research investments aimed at transforming computers from specialized tools to partners in problem-solving,” said Dr. Walker. “Today, machines lack contextual reasoning capabilities, and their training must cover every eventuality, which is not only costly, but ultimately impossible. We want to explore how machines can acquire human-like communication and reasoning capabilities, with the ability to recognize new situations and environments and adapt to them.”

DARPA is currently pursuing more than 20 programs that are exploring ways to advance the state-of-the-art in AI, pushing beyond second-wave machine learning techniques towards contextual reasoning capabilities. In addition, more than 60 active programs are applying AI in some capacity, from agents collaborating to share electromagnetic spectrum bandwidth to detecting and patching cyber vulnerabilities. Over the next 12 months, DARPA plans to issue multiple Broad Agency Announcements for new programs that advance the state of the art in AI.

Under AI Next, key areas to be explored may include automating critical DoD business processes, such as security clearance vetting in a week or accrediting software systems in one day for operational deployment; improving the robustness and reliability of AI systems; enhancing the security and resiliency of machine learning and AI technologies; reducing power, data, and performance inefficiencies; and pioneering the next generation of AI algorithms and applications, such as “explainability” and commonsense reasoning.

In addition to new and existing DARPA research, a key component of the campaign will be DARPA’s Artificial Intelligence Exploration (AIE) program, first announced in July 2018. “In today’s world of fast-paced technological advancement, we must work to expeditiously create and transition projects from idea to practice,” said Dr. Walker.

Accordingly, AIE constitutes a series of high-risk, high payoff projects where researchers will work to establish the feasibility of new AI concepts within 18 months of award. Leveraging streamlined contracting procedures and funding mechanisms will enable these efforts to move from proposal to project kick-off within three months of an opportunity announcement.
