Flexible electronics is a rapidly growing technology for a multitude of applications. Wearables and flexible displays are some application examples. Various technologies and processes are used to produce flexible electronics. An important aspect to be considered when developing these systems is their reliability, especially with regard to repeated bending. In this paper, the frequently used methods for investigating the bending reliability of flexible electronics are presented. This is done to provide an overview of the types of tests that can be performed to investigate the bending reliability. Furthermore, it is shown which devices are developed and optimized to gain more knowledge about the behavior of flexible systems under bending. Both static and dynamic bending test methods are presented.

The stretchable electrodes with excellent flexibility, electrical conductivity, and mechanical durability are the most fundamental components in the emerging and exciting field of flexible electronics. This article proposes a method for fabrication of such a stretchable electrode by embedding silver nanorods (AgNRs) into a polydimethylsiloxane (PDMS) matrix that is grown by a unique glancing angle deposition technique. The surface, mechanical, and electrical properties of PDMS are significantly changed after embedding the AgNRs in it. The results show that surface roughness and polarity increase after AgNRs are embedded in the PDMS matrix. Elastic modulus (E) and hardness (H) decrease with an increase in the indentation load as a result of the indentation depth effect. Due to strong interfacial adhesion of AgNRs embedded in the PDMS matrix, the E and H of nanocomposite are increased by 167.6 and 93.3% compared with PDMS film, respectively. Furthermore, the AgNRs-PDMS film has an electrical resistivity value in the order of 10 −7 Ωm. It remains conductive during various mechanical strains such as bending, twisting, and stretching, which is demonstrated using a light-emitting diode circuit. Simultaneously, the antimicrobial activity of silver could make it a promising candidate for wearable electronics.

To ensure the safety and reliability of increasingly frequent, long‐duration, and long‐distance space missions, a sufficient and timely supply of the electronics and sensors that are essential in the maintenance and regeneration of spacecraft in space has become urgent. Solution‐based printing (SP) in space can be considered a disruptive technology for in situ manufacturing and maintenance of functional devices during the long duration and endurance of space exploration and crewed spaceﬂight. Herein, the origin and overview of the printing techniques in space are first introduced and further the printing processes in extreme space environments are discussed; then, its potential space applications in flexible solar cells, soft and wearable sensors, and space‐based antennas are forecast; finally, survivability for printed electronics in space is analyzed. Overall, a comprehensive description of the applicability and application of the SP techniques for manufacturing electronics and sensors in space is given.
