“…The development of flexible electronics overcome the disadvantage that inorganic electronics cannot be integrated on curved surfaces, so applications of electronic products have been greatly expanded. Flexible transistors, flexible capacitors and flexible sensors are typical flexible electronic components; all have been integrated into complex circuits for applications in health care (Ray et al, 2019;Chung et al, 2020;Hanna et al, 2020;Jin et al, 2020;Ma et al, 2020;Madhvapathy et al, 2020;Sun et al, 2020;Zhou et al, 2020).…”

Flexible electronics has attracted tremendous attention in recent years. The essential requirements for flexible electronics include excellent electrical properties, flexibility and stretchability. By introducing special structures or using flexible materials, electronic devices can be given excellent flexibility and stretchability. In this paper we review the realization of flexible electronics from the perspective of structural design strategies and materials; then, healthcare application of flexible electronic systems was introduced. Finally, a brief summary and outlook are presented.

Smart piezoelectric materials are of great interest due to their unique properties. Piezoelectric materials can transform mechanical energy into electricity and vice versa. There are mono and polycrystals (piezoceramics), polymers, and composites in the group of piezoelectric materials. Recent years show progress in the applications of piezoelectric materials in biomedical devices due to their biocompatibility and biodegradability. Medical devices such as actuators and sensors, energy harvesting devices, and active scaffolds for neural tissue engineering are continually explored. Sensors and actuators from piezoelectric materials can convert flow rate, pressure, etc., to generate energy or consume it. This paper consists of using smart materials to design medical devices and provide a greater understanding of the piezoelectric effect in the medical industry presently. A greater understanding of piezoelectricity is necessary regarding the future development and industry challenges.

“…Flexible/stretchable electronics attached to dynamically changing, curvilinear surfaces can still function properly upon various mechanical deformations, including stretching, bending, and twisting [1]. The integration of sensors and actuators with data communication and powering modules in this class of emerging electronics enables its applications in energy generator/storage [2][3][4][5][6], human-machine interfaces [7,8], health monitoring [9,10], and clinical treatments [11]. The commonly used strategies in the design and fabrication of flexible/stretchable electronics rely on either intrinsically stretchable materials [12,13] or stretchable structures [14][15][16][17][18].…”

As the key component of wireless data transmission and powering, stretchable antennas play an indispensable role in flexible/stretchable electronics. However, they often suffer from frequency detuning upon mechanical deformations; thus, their applications are limited to wireless sensing with wireless transmission capabilities remaining elusive. Here, a hierarchically structured stretchable microstrip antenna with meshed patterns arranged in an arched shape showcases tunable resonance frequency upon deformations with improved overall stretchability. The almost unchanged resonance frequency during deformations enables robust on-body wireless communication and RF energy harvesting, whereas the rapid changing resonance frequency with deformations allows for wireless sensing. The proposed stretchable microstrip antenna was demonstrated to communicate wirelessly with a transmitter (input power of − 3 dBm) efficiently (i.e., the receiving power higher than − 100 dBm over a distance of 100 m) on human bodies even upon 25% stretching. The flexibility in structural engineering combined with the coupled mechanical–electromagnetic simulations, provides a versatile engineering toolkit to design stretchable microstrip antennas and other potential wireless devices for stretchable electronics.
