Special Issue Information

Dear Colleagues,

Electronic devices have evolved into highly flexible, curvilinear, and stretchable formats that enable new biomedical, robotic, and consumer-health-related applications.

The rapid development of soft/stretchable inorganic/organic electronics, wireless communication modules, biosensors, and soft encapsulating substrates has underlain this ascension in recent years. As a result, major advances have been achieved in system-level mechanics, with implications for emerging biomedical devices, human–machine interface designs, e-skins, prosthetics, surgical/nonsurgical robotics, plastronics, and flexible optical instruments for imaging and telecommunication.

After more than two decades of academic and industry research, this new class of electronics is poised to have a commercial impact. To achieve this translational feat, there are several important challenges that are being addressed today, including the development of effective encapsulation; robust circuity and interconnects; mechanical robustness; long term stability; etc.

We envision a collection of paper that address these major challenges. Use cases, devices, and applications of flexible/stretchable sensors will form part of this Special Issue, which will include research with a focus on materials and approaches to tailor soft and stretchy electronics, medical devices, sensors and systems that exploit soft/stretchable electronics, and their applications. The issue will also cover core technology capabilities, including synthesis, fabrication, characterization, and modeling approaches, along with translational applications that highlight system-level deployment in the field.

We present a thin and elastic tactile sensor glove for teaching dexterous manipulation tasks to robots through human demonstration. The entire glove, including the sensor cells, base layer, and electrical connections, is made from soft and stretchable silicone rubber, adapting to deformations under bending and contact while preserving human dexterity. We develop a glove design with five fingers and a palm sensor, revise material formulations for reduced thickness, faster processing and lower cost, adapt manufacturing processes for reduced layer thickness, and design readout electronics for improved sensitivity and battery operation. We further address integration with a multi-camera system and motion reconstruction, wireless communication, and data processing to obtain multimodal reconstructions of human manipulation skills.

The rapid development of electronic material and sensing technology has enabled research to be conducted on liquid metal-based soft sensors. The application of soft sensors is widespread and has many applications in soft robotics, smart prosthetics, and human-machine interfaces, where these sensors can be integrated for precise and sensitive monitoring. Soft sensors can be easily integrated for soft robotic applications, where traditional sensors are incompatible with robotic applications as these types of sensors show large deformation and very flexible. These liquid-metal-based sensors have been widely used for biomedical, agricultural and underwater applications. In this research, we have designed and fabricated a novel soft sensor that yields microfluidic channel arrays embedded with liquid metal Galinstan alloy. First of all, the article presents different fabrication steps such as 3D modeling, printing, and liquid metal injection. Different sensing performances such as stretchability, linearity, and durability results are measured and characterized. The fabricated soft sensor demonstrated excellent stability and reliability and exhibited promising sensitivity with respect to different pressures and conditions. Full article
