Iontronic sensing paper provides a new touch for pressure sensors (w/video)

Thu, 03/28/2019 - 02:57
Recently, a brand-new mechanism of pressure sensing, known as flexible iontronic sensing (FITS), has been introduced, which utilizes pressure-induced capacitive changes between electrodes and ionic surfaces. Researchers have used FITS to develop a single-sheet iontronic paper substrate with both ionic and conductive patterns as an all-in-one flexible sensing platform. This novel paper sensor extends the iontronic sensing principle to a more adaptive material system, with direct printability, custom cuttability, and 3D foldability at a low cost - just as regular paper.

Bacteria could become a future source of electricity

Wed, 03/27/2019 - 01:31
In recent years, researchers have tried to capture the electrical current that bacteria generate through their own metabolism. So far, however, the transfer of the current from the bacteria to a receiving electrode has not been efficient at all. Now, they have achieved a slightly more efficient transfer of electrical current.
