Tactile Sensors
In article number 2203193, Jongbaeg Kim and co‐workers develop a resistive tactile sensor based on a carbon nanotube (CNT)‐embedded/‐coated dual‐scale porous structure. This sensor exhibits a highly sensitive and linear response over a wide pressure range. With a demonstration of monitoring various human movements, the sensor can be a promising candidate for a health monitoring devices...
Porous structures have been utilized in tactile sensors to improve sensitivity owing to their excellent deformability. Recently, tactile sensors using porous structures have been used in practical applications, such as bio‐signal monitoring. However, highly sensitive responses are limited to the low‐pressure range, and their sensitivity significantly decreases in a higher‐pressure range. Several approaches...
Resistive tactile sensors based on changes in contact area have been extensively explored for a variety of applications due to their outstanding pressure sensitivity compared to conventional tactile sensors. However, the development of tactile sensors with high sensitivity in a wide pressure range still remains a major challenge due to the trade‐off between sensitivity and linear detection range....
In article number 1902484, Jongbaeg Kim and co‐workers develop a highly sensitive, flexible tactile sensor composed of stacked carbon nanotube‐ and Ni‐coated fabrics. With a scalable and cost‐effective fabrication technique, this conceptually simple yet powerful approach not only efficiently utilizes the excellent properties of fabrics but also achieves high sensitivity and linearity over an extremely...
In this paper, we present a flexible hybrid energy harvester for single- or multi-source energy collection. To increase harvesting power, piezoelectric and thermoelectric conversions are used simultaneously. The piezoelectric portion of the harvester collects energy from low-frequency kinetic motion using frequency up-conversion. The thermoelectric part is suitable for harvesting energy from a curved...
Although there have been remarkable improvements in stretchable strain sensors, the development of strain sensors with scalable fabrication techniques and which both high sensitivity and stretchability simultaneously is still challenging. In this work, a stretchable strain sensor based on overlapped carbon nanotube (CNT) bundles coupled with a silicone elastomer is presented. The strain sensor with...
Low‐dimensional carbon materials, such as semiconducting carbon nanotubes (CNTs), conducting graphene, and their hybrids, are of great interest as promising candidates for flexible, foldable, and transparent electronics. However, the development of highly photoresponsive, flexible, and transparent optoelectronics still remains limited due to their low absorbance and fast recombination rate of photoexcited...
In article number 1700918, Jungwook Choi, Jongbaeg Kim, and co‐workers, develop a flexible/stretchable, fully transparent, and highly sensitive photodetector based on heterogeneously integrated porphyrin–single‐walled carbon nanotube (SWNT)–graphene. The all‐carbon optoelectronic device is constructed from monolayer graphene electrodes, and uniformly dispersed SWNT networks as semiconducting channels...
We have developed a highly sensitive pressure sensor using carbon nanotube (CNT)-coated polyester fabric. With simple and cost-effective dip-coating process using CNT ink, we produced conductive polyester fabric, and its resistance could be controlled easily by modulating dipping number. When the pressure is applied, the highly porous structure of the fabric allows the dramatic improvement of the...
