Increasingly, recognizing the context in which data is generated is more relevant than the raw sensor data itself. While sophisticated machine learning algorithms can process raw data to generate context, the ability to generate and record data has surpassed the capacity to make sense of it efficiently.
The next paradigm in sensing systems is to integrate sensing and cognition at the sensor level, enabling pattern detection in data as it arrives without the need for extensive data transmission. This talk covers three such physical computers based on physical Reservoir Computing (RC) to detect patterns in data. First, an electrothermal computer is built using off-the-shelf components to tackle sophisticated contextual computations, including standard benchmarks and real-time event detection. We then demonstrated similar capabilities based on 3D-printed computers for near-sensor signal processing. Finally, we will discuss the evolution of the work into building a 3D-printed computer with concurrent sensing and computing capabilities as a demonstration of in-sensor computing. We conclude with potential roadmaps for future research and a diversity of applications that can benefit from its results.
