“…The demonstration by the group of J.A. Rogers, that also silicon nanomembranes 34 and other layered materials can be wrinkled to withstand large tensile deformations 35,36 , rendered functional electronic components and entire logic circuits to become stretchable 9 . A large variety of compliant organic and inorganic electronic elements with various functions have been realized in the last years, which are summarized in figure 1.1.…”

“…Furthermore, it can lead to biaxial stretchability if the elastomeric substrate is pre-stretched in both lateral dimensions 36 . As shown in figure 2.13c, these features have led to the design of more functional and highly integrated stretchable electronic systems relying on surface wrinkling 9,13,40,41 .…”

“…This is beneficial to achieve higher stretchabilities without inducing cracks in the functional magnetic layer. Another advantage of this approach is that the direction of the pre-strain can be controlled in order to either prepare systems that are compliant along one defined axis or even achieve biaxial stretchability 36 .…”

Abstract:In this work, stretchable magnetic sensorics is successfully established by combining metallic thin films revealing a giant magnetoresistance effect with elastomeric materials. Stretchability of the magnetic nanomembranes is achieved by specific morphologic features (e.g. wrinkles), which accommodate the applied tensile deformation while maintaining the electrical and magnetic integrity of the sensor device. The entire development, from the demonstration of the world-wide first elastically stretchable magnetic sensor to the realization of a technology platform for robust, ready-touse elastic magnetoelectronics with fully strain invariant properties, is described. The prepared soft giant magnetoresistive devices exhibit the same sensing performance as on conventional rigid supports, but can be stretched uniaxially or biaxially reaching strains of up to 270% and endure over 1,000 stretching cycles without fatigue. The comprehensive magnetoelectrical characterization upon tensile deformation is correlated with in-depth structural investigations of the sensor morphology transitions during stretching.With their unique mechanical properties, the elastic magnetoresistive sensor elements readily conform to ubiquitous objects of arbitrary shapes including the human skin. This feature leads electronic skin systems beyond imitating the characteristics of its natural archetype and extends their cognition to static and dynamic magnetic fields that by no means can be perceived by human beings naturally.Various application fields of stretchable magnetoelectronics are proposed and realized throughout this work. The developed sensor platform can equip soft electronic systems with navigation, orientation, motion tracking and touchless control capabilities. A variety of novel technologies, like smart textiles, soft robotics and actuators, active medical implants and soft consumer electronics will benefit from these new magnetic functionalities.

“…Metal films on PDMS, however, can sustain only limited stretching, and the stable and durable deposition of metal onto PDMS surfaces poses a great challenge. Several ingenious solutions to this problem have been described, including an accordionlike structure 18,19 , a meandering-shaped thin metal conductor on the PDMS surface 3,12,17,[19][20][21] , bonding of two-dimensional stretchable Si nanomembranes onto elastomeric PDMS slabs, or printing of elastic conductors comprising single-walled nanotubes on elastic substrates [22][23][24] . Although these technologies have contributed greatly to the development of flexible electronics, each of them still has their limits (for example, complicated fabrication processes, and direct bonding of commercialized components on highly stretching substrates).…”

A variety of flexible and stretchable electronics have been reported for use in flexible electronic devices or biomedical applications. The practical and wider application of such flexible electronics has been limited because commercial electronic components are difficult to be directly integrated into flexible stretchable electronics and electroplating is still challenging. Here, we propose a novel method for fabricating flexible and stretchable electronic devices using a porous elastomeric substrate. Pressurized steam was applied to an uncured polydimethylsiloxane layer for the simple and cost-effective production of porous structure. An electroplated nickel anchor had a key role in bonding commercial electronic components on elastomers by soldering techniques, and metals could be stably patterned and electroplated for practical uses. The proposed technology was applied to develop a plaster electrocardiogram dry electrode and multi-channel microelectrodes that could be used as a long-term wearable biosignal monitor and for brain signal monitoring, respectively.
