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

Nanowerk - Wed, 03/27/2019 - 6:57pm
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.
