Highly transparent tactile sensor based on a percolated carbon nanotube network

This is the authors' abstract. We don't add key points for this paper.

The demand for transparent and flexible electronic devices, which are an emerging technology for the next generation of sensors, continues to grow in both applications and development due to their potential to make a significant commercial impact in a wide variety of areas. Here, we demonstrate a highly transparent tactile sensor with 92% optical transparency in the visible range based on solution-processed 99% metallic CNTs attached on a polydimethylsiloxane (PDMS) film. We efficiently reconstructed the pressed, stimulated spatial location by increasing the injection current (Iinjection) during electrical resistance tomography (ERT) that computed the internal two-dimensional (2-D) resistivity distribution.
