Lithium ion batteries are the subject of much globalattention in the continuing development of advanced energystorage technologies. To date, these batteries offer the bestcombination of energy capacity per gram, cost, and long termcycle stability. However, lithium ion batteries have severaldisadvantages. The materials used in Li-ion batteries arerelatively costly, while capacity is ultimately limited...
Wearable sensors, capable of detecting various motions of the human body, present unique opportunities for the development of advanced electronic interfaces. Such sensors have widespread applications in robotics, medicine, and electronic gaming. Capacitive sensors have numerous advantages. They are physically robust, can be constructed from a variety of materials in different shapes and sizes, and...
Planar Strain mapping of interconnects, such as Ball Grid Arrays (BGA) and Through-Silicon Vias (TSVs), is an important step in the development and testing of electronics packages, as excessive strain can lead to device failure. Today, the two most widely adopted methods of experimental strain field measurement, Digital Image Correlation and Moiré Interferometry, encounter limitations when the average...
Stretchable and flexible electronic devices have gained significant attention in recent years, as they can be integrated into many systems such as medical sensors, displays, and robots. One of the primary areas of research is designing stretchable interconnects which provide adequate conductivity and mechanical robustness. Metal-based interconnects have been reported to have the highest conductivity,...
Strain distribution exists in all microelectronic devices, including emerging flexible[1] and foldable[2] electronics. When a device is subject to bending or elevated temperature, the mechanical and electrical properties change. In some cases induced or applied strain can cause the device to fail[3–5]. For this reason, accurate strain mapping techniques are of great interest[6] to the electronics...
