The semiconductor chips driving modern-day computer processors are covered in billions of individual transistors, each of which can overheat under stress, causing steep drops in performance. To address this, a team led by researchers at Penn State has developed a microscopic thermometer, smaller than an ant’s antenna, that can be integrated onto a chip to accurately track temperatures.

Making computer chips smaller is not just about better design. It also depends on a critical step in manufacturing called patterning, where nanoscale structures are carved into materials to form the circuits inside everything from smartphones to advanced sensors.
To create these patterns, engineers use a hard mask, a thin, durable material layer that protects selected regions while the exposed areas are etched away.

Power sources used in devices found in or around biological tissue must be flexible and non-toxic, while still powerful enough to support demanding technologies such as medical devices or soft robotics. To achieve this balance, researchers at Penn State are taking inspiration from a “shocking” place: electric eels.
