I do research on communication and computation systems composed of extremely simple elements that derive their functionality from interactions with each other. Such highly distributed systems are easy to manage, low in energy consumption, robust to defects of elements, and cheap to manufacture, yet they will allow users to gain a powerful control and understanding of their environment. Neural systems have been my special research interest, because of their innate ability to represent and process information in real time through simple interactions.

My lab aims to develop wireless sensor networks that consist of huge numbers of extremely simple nodes, each being at most 1 mm in any dimension, consuming only power provided to it by its environment, and costing less than 1 Yen to mass manufacture. Key requirements are the use of pulse-based signaling both inside nodes as well as between nodes. Nodes collaborate to obtain information about the environment by combining pulses from other nodes through strategies resembling those found in the brain, like synchronization and desynchronization of pulse trains and the use of spatial temporal activation patterns.

The pulse-based wireless sensor networks we are developing will be employed cost-effectively in much higher densities than currently possible by conventional wireless sensor networks. This should allow much faster and precise detection of anomalies in the environment (such as chemical disasters), as well as real-time monitoring. Due to the small size and low cost of nodes, no retrieval of nodes after use is necessary, and their energy harvesting ability will allow them to be active for extended periods of time without maintenance. New applications become possible, like attaching sensor nodes to insects, spreading sensor nodes in the air, and applying sensor nodes to surfaces.
