Highly Sensitive Dopamine Detector Uses 2D Materials
A supersensitive dopamine detector can help in the early diagnosis of several disorders that result in too much or too little dopamine, according to a group led by Penn State.
Locust Swarm Could Improve Collision Avoidance
A team of engineers is creating a low-power collision detector that mimics the locust avoidance response and could help robots, drones and even self-driving cars avoid collisions.
An Improved Wearable, Stretchable Gas Sensor Using Nanocomposites
A stretchable, wearable gas sensor for environmental sensing has been developed and tested by researchers at Penn State, Northeastern University and five universities in China.
To Make A Better Sensor, Just Add Noise
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.
