Flexible Highly Sensitive Pressure Sensor Based on Ionic Liquid Gel Film

TL;DR: Flexible capacitive pressure sensors that incorporate micropatterned pyramidal ionic gels to enable ultrasensitive pressure detection are presented, offering a simple, robust approach to low-cost, scalable device design, enabling practical applications of electronic skin.

TL;DR: In the past decade, a brand-new pressure and tactile-sensing modality known as iontronic sensing has emerged, utilizing the supercapacitive nature of the electrical double layer (EDL) that occurs at the electrolytic-electronic interface, leading to ultrahigh device sensitivity, high noise immunity, high resolution, high spatial definition, optical transparency, and responses to both static and dynamic stimuli, in addition to thin and flexible device architectures.

TL;DR: Owing to the ultrahigh sensitivity, the as-fabricated sensor will have great potential for wearable devices in health status monitoring, motion detection, and electronic skin.

TL;DR: Ionic flexible sensors (IFS) as mentioned in this paper are one kind of advanced sensors that are based on the concept of ion migration, which can not only replicate the topological structures of human skin, but also are capable of achieving tactile perception functions similar to human skin.

TL;DR: This Review will cover materials and devices designed for mimicking the skin's ability to sense and generate biomimetic signals.

TL;DR: An efficient, low-cost fabrication strategy to construct a highly sensitive, flexible pressure sensor by sandwiching ultrathin gold nanowire-impregnated tissue paper between two thin polydimethylsiloxane sheets is reported, enabling facile large-area integration and patterning for mapping spatial pressure distribution.

TL;DR: Integration of organic transistors and rubber pressure sensors, both of which can be produced by low-cost processing technology such as large-area printing technology, will provide an ideal solution to realize a practical artificial skin.

TL;DR: It is demonstrated that the flexible pressure-sensitive organic thin film transistors fabrication can be used for non-invasive, high fidelity, continuous radial artery pulse wave monitoring, which may lead to the use of flexible pressure sensors in mobile health monitoring and remote diagnostics in cardiovascular medicine.
