Wearable sensors are evolving from watches and electrodes to bendable devices that provide far more precise biometric measurements and comfort for users. Now, an international team of researchers has taken the evolution one step further by printing sensors directly on human skin without the use of heat.
Led by Huanyu “Larry” Cheng, Dorothy Quiggle Career Development Professor in the Penn State Department of Engineering Science and Mechanics, the team published their results in ACS Applied Materials & Interfaces.
“In this article, we report a simple yet universally applicable fabrication technique with the use of a novel sintering aid layer to enable direct printing for on-body sensors,” said first author Ling Zhang, a researcher in the Harbin Institute of Technology in China and in Cheng’s laboratory.
Cheng and his colleagues previously developed flexible printed circuit boards for use in wearable sensors, but printing directly on skin has been hindered by
Amazon wants to make your offline shopping experience a lot more contactless. The e-commerce company is introducing a new biometric technology that can identify you and verify your credit card purchases at stores by simply scanning your palm.
Called Amazon One, this technology will soon begin showing up in Amazon’s own retail stores — starting with two of the company’s Amazon Go outlets in Seattle.
However, Amazon says it’s planning to license the tech to third parties as well and expand beyond just contactless payments. With Amazon One, employees could, for instance, authenticate themselves into offices using their palms or customers could use their loyalty subscriptions at stores without the need to always physically carry the cards. Essentially, Amazon hopes to turn your palm into an all-encompassing ID system for all your cards and identification with Amazon One.
Amazon One will be available inside terminals at the entrance of stores
Amazon has developed a new biometric ID system that works by scanning the palms of participating customers, planning to ultimately let people make in-store payments, gain access to office buildings, and move quickly through stadium turnstiles by holding out a hand.
The system, called “Amazon One,” comes with numerous safeguards designed to protect user data. Even so, Amazon’s use of biometrics in stores and other commercial settings promises to attract scrutiny at a time of heightened awareness of digital security and privacy, testing the limits of customer trust in the company.
Amazon One is set to debut Tuesday at two Amazon Go convenience stores near the company’s Seattle headquarters, giving customers an alternative to the regular process of checking into
