Printed Electronics Due to the stretchability, non-toxicity, and ultra-low-cost, printed electronics (PE) dominates the innovative areas such as wearable technology and Internet of Things (IoT) infrastructures. In contrast to silicon-based technology, PE is additive manufacturing that allows high-degree customization and low-amount production, and thus has received considerable interest in edge-AI community.

Artificial neural networks (ANNs) ANNs simulate the human nervous system and have a solid ability to deal with non-linear problems. Besides, the learning-based optimization allows them an extremely high efficiency in designing their parameters. Further, the ultra-simplicity of their computing units (weighted-sum & activation) are ideal for the hardware implementation in PE. A promising approach it is the printed neuromorphic computing system.

Printed neuromorphics Despite the availability of a large number of computing units in the field of ubiquitous computing and edge-AI (such as Arduino and mobile phones), the cost and extravagant computing resources can still be saved by printed neuromorphic systems. Printed neuromorphics are the hardware implementation of ANN using resistors, transistors, etc. However, the emerging printed neuromorphics are not perfect. However, due to the hardware-limitation, the components in

Goal of thesis implement the learnable inverter and activation function for the printed neuromorphics.
