In a sensing phenomenon common in the animal world but unusual in manmade sensors, Penn State researchers have added a small amount of background noise to enhance very weak signals, in this case a light source too dim to sense.
Wearable and implantable devices are currently used for a variety of functions, including health tracking and monitoring.
A new type of imaging that does not require a lens and uses reconfigurable particle-based masks to take multiple shots of an object is being developed by researchers at Penn State.
A team of researchers suggests that using two thin films of different materials may be the way to go to create affordable, thin film cells with about 34% efficiency.
