Nature and Human-Inspired Sensing Devices

B10- Bioinspired Organic Materials and Devices for Sensing and Computing

Sensing systems provide timely¹ and requisite data for machines to operate in physical environments. Often, natural biological systems provide optimized concepts that could be applied to design and engineer artificial sensor systems. Novel organic-based materials can even provide self-healing capabilities to such sensor devices². In this talk, I will discuss our recent advances in nature- and human-inspired materials for designing high performance sensor devices^3,4. The exciting cross-disciplinary interplay of physical interfaces, materials chemistry and electronics become essential for optimizing sensitivity, linearity and speed for the sensor system.
