A review on polymers and their composites for flexible electronics

Flexible Tactile Sensing Based on Piezoresistive Composites: A Review

The large expansion of the robotic field in the last decades has created a growing interest in the research and development of tactile sensing solutions for robot hand and body integration. Piezoresistive composites are one of the most widely employed materials for this purpose, combining simple and low cost preparation with high flexibility and conformability to surfaces, low power consumption...

Physical Aging of Epoxy Polymers and Their Composites

Exposure to extended periods of sub-Tg temperatures causes physical changes in the molecular structure of epoxy resins and epoxy-based materials to occur. These physical aging mechanisms include the reduction in free volume and changes to the molecular configuration. As a result, mechanical, thermodynamic, and physical properties are affected in ways that can compromise the reliability of epoxy...

On the Physics Required for Prediction of Long Term Performance of Polymers and Their Composites

National Institute of Standards and Technology, Gaithersburg, MD 20899-0001 The long term performance of polymers and their composites is an important aspect of their increasing use in engineering applications. Temporal, thermal, and mechanical stresses can all contribute to the deterioration of performance. Here we examine the concepts of the physics of glassy polymers and how they are importa...

Stretchable electronics based on Ag-PDMS composites

Patterned structures of flexible, stretchable, electrically conductive materials on soft substrates could lead to novel electronic devices with unique mechanical properties allowing them to bend, fold, stretch or conform to their environment. For the last decade, research on improving the stretchability of circuits on elastomeric substrates has made significant progresses but designing printed ...
