Capacitive sensors work by detecting the change of capacitance introduced by the finger touching near the electrode. Such change is so small that detecting it unambiguously is challenging, and has ...

Researchers from Skoltech, MIPT, and the RAS Institute of Nanotechnology of Microelectronics have achieved a five-fold increase in the capacitance of carbon nanowalls, a material used in the ...

Capacitive deionisation (CDI) is a promising alternative technology in desalination (Welgemoed and Schutte 2005; Farmer et al. 1997; Oren, 2008) which is particularly suitable for small-scale inland ...

By increasing the electron energy in the metal, raising the Fermi level above E0, electrons can be transferred to the acceptor, creating more ions in the reduced state and decreasing the number in the ...

Scientists have reported unprecedented performance results for a supercapacitor electrode. The researchers fabricated electrodes using a printable graphene aerogel to build a porous three-dimensional ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

Blue energy, which is the free energy lost when salty sea water and less salty river water meet and mix in estuaries, could become a significant source of global electricity in the future. Capacitive ...

As one after another handheld consumer electronics gadgets such as tablets and smartphones emerges in the market, touch panel technology, with its capability to enable smaller devices, lower ...

The inverters and charging systems in hybrid or fully electric vehicles provide a topical example of a high-voltage application that faces extreme space constraints. When multilayer ceramic capacitors ...
