A Scalable Networked Smart Sensate Skin


We have developed tightly coupled sensor network that tries to mimic some of the sensory characteristics of a natural skin. Developed in a flexible substrate (Kapton Polyimide), this array forms a flexible surface of small, networked sensor elements. Each node is capable of sensing four channels of pressure, two axes of strain, sound, temperature, ambient light, and two channels of whisker mechanoreception. By seamlessly blending sensing, computation, and local and global networking, our "skin" is ultimately self-configuring and scalable�it can be built as large as desired and signals can be extracted from the entire array at any node.
