We report on investigation of the mechanical properties of paper electronics (printed and made out of paper). One key objective of such paper electronics is to achieve ultraflexibility. Therefore, it is important to understand electrical functionality and reliability of paper electronics under various physical (mechanical) deformations. Here, we show the general mechanical properties of the cellulose...
Freeform (physically flexible, stretchable and reconfigurable) electronics can be critical enabler for advanced personalized healthcare. With increased global population and extended average lifetime of mankind, it is more important than ever to integrate advanced electronics into our daily life for advanced personalized healthcare. In this paper, we discuss some critical criteria to design such electronics...
A design strategy for fully flexible electrode arrays with out‐of‐plane through polymer vias (TPVs) for monolithic 3D integration of sensor readout circuitry is presented. The TPVs are formed using copper embedded in thin polyimide structure for support. The copper interconnects offer a stable impedance frequency response from DC to 100 kHz (Z ≈ 20 Ω, θ ≈ 0°).
On page 5141, A. M. Hussain and M. M. Hussain report a process for fabricating electronics and sensor arrays on the opposite sides of the same flexible polymer, which can lead to the development of high resolution brain machine interfaces (BMI). The fabrication is done monolithically in a single process‐flow, following which the polymer is released to obtain a flexible device with sensors on one side...
