A simple, yet versatile, new design for chaotic oscillating circuitry inspired by prime numbers

Researchers have found a simple, yet highly versatile, way to generate 'chaotic signals' with various features. The technique consists of interconnecting three 'ring oscillators,' effectively making them compete against each other, while controlling their respective strengths and their linkages. The resulting device is rather small and efficient, thus suitable for emerging applications such as realizing wireless networks of sensors.
