A. N. Frumkin used surface charge to change the shape of water drops in 1936. [2] The term electrowetting was first introduced in 1981 by G. Beni and S. Hackwood to describe an effect proposed for designing a new type of display device for which they received a patent. [3]
Optoelectrowetting (OEW) is a method of liquid droplet manipulation used in microfluidics applications. This technique builds on the principle of electrowetting, which has proven useful in liquid actuation due to fast switching response times and low power consumption.
Digital microfluidics (DMF) is a platform for lab-on-a-chip systems that is based upon the manipulation of microdroplets. Droplets are dispensed, moved, stored, mixed, reacted, or analyzed on a platform with a set of insulated electrodes.
The water drops maintain their spherical shape due to the superhydrophobicity of the petal (contact angle of about 152.4°), but do not roll off because the petal surface has a high adhesive force with water. [41] When comparing the "petal effect" to the "lotus effect", it is important to note some striking differences. The surface structure of ...
Replacing the conductor with a semiconductor results in asymmetrical electrowetting behavior (in terms of voltage polarity), depending on the semiconductor doping type and density. Incident light above the semiconductor's band gap creates photo-induced carriers via electron-hole pair generation in the depletion region of the underlying ...
As wildfires burned across Los Angeles County, burning more than 12,000 structures, many of them homes, two mothers launched a grassroots project to reunite displaced children with their beloved ...
Because your little one deserves to enjoy water activities to the fullest. Whether you’re at the pool, the beach, or the lake, it’s important to protect your kids’ sensitive feet. These ...
The Soup Drops retail for $2.49, plus 99 cents shipping, the news release said. The 20-pack of Soup Drops comes packaged in "a can that looks just like the iconic Progresso Soup can," as well as a ...
