An international team of researchers have developed a low-cost sensor made from semiconducting plastic that can be used to diagnose or monitor a wide range of health conditions, such as surgical complications or neurodegenerative diseases. The sensor can measure the amount of critical metabolites, such as lactate or glucose, that are present in sweat, tears, saliva or blood, and, when incorporated into a diagnostic device, could allow health conditions to be monitored quickly, cheaply and accurately...

Instead of ordering batteries by the pack, we might get them by the ream in the future. Researchers at Binghamton University, State University of New York have created a bacteria-powered battery on a single sheet of paper that can power disposable electronics. The manufacturing technique reduces fabrication time and cost, and the design could revolutionize the use of bio-batteries as a power source in remote, dangerous and resource-limited areas.

“Papertronics have recently emerged as a simple and low-cost way to power disposable point-of-care diagnostic sensors,” said Assistant Professor Seokheun “Sean...

A new disposable battery that folds like an origami ninja star could power biosensors and other small devices for use in challenging field conditions. Seokheun “Sean” Choi, assistant professor of computer and electrical engineering at Binghamton University, along with 2 of his students, developed the device, a microbial fuel cell that runs on the bacteria available in a few drops of dirty water.

Choi previously developed a paper-based origami battery. The first design, shaped like a matchbook, stacked 4 modules together. The ninja star version, which measures about 2...
