“…For printable chemical sensors used for non-biological analytes in solid and liquid media, organic semiconductors hold particular promise due to their ease of fabrication, biocompatibility, customizable functionality and mechanical flexibility. Among the various available organic semiconductors, poly (3,4-ethylenedioxythiophene) polystyrene sulfonate is the most widely used due to its ease of processing, stability in aqueous environments, high conductivity, and compatibility with printing techniques (figure 57) [545]. Over the past decade, several reports have demonstrated the successful use of solution-processable semiconductors with printing processes for developing organic chemical sensors for non-biological analytes in solid and liquid media.…”

The dissemination of sensors is key to realizing a sustainable, ‘intelligent’ world, where everyday objects and environments are equipped with sensing capabilities to advance the sustainability and quality of our lives—e.g., via smart homes, smart cities, smart healthcare, smart logistics, Industry 4.0, and precision agriculture. The realization of the full potential of these applications critically depends on the availability of easy-to-make, low-cost sensor technologies. Sensors based on printable electronic materials offer the ideal platform: they can be fabricated through simple methods (e.g., printing and coating) and are compatible with high-throughput roll-to-roll processing. Moreover, printable electronic materials often allow the fabrication of sensors on flexible/stretchable/biodegradable substrates, thereby enabling the deployment of sensors in unconventional settings. Fulfilling the promise of printable electronic materials for sensing will require materials and device innovations to enhance their ability to transduce external stimuli—light, ionizing radiation, pressure, strain, force, temperature, gas, vapours, humidity, and other chemical and biological analytes. This Roadmap brings together the viewpoints of experts in various printable sensing materials—and devices thereof—to provide insights into the status and outlook of the field. Alongside recent materials and device innovations, the roadmap discusses the key outstanding challenges pertaining to each printable sensing technology. Finally, the Roadmap points to promising directions to overcome these challenges and thus enable ubiquitous sensing for a sustainable, ‘intelligent’ world.

“…Multimodal sensing capabilities are indispensable in bioelectronic applications for complicated diagnoses and smart healthcare. In general, multimodal neuromorphic devices with multiple perceptual abilities are realized by integrating multiple sensing units [72,170,171]. For example, as illustrated in figure 8(a), Takemoto et al integrated a fully transparent flexible OECT with a photodetector, near-infrared laser, and micro-light-emitting diode (µ-LED) to monitor mental stress from the perspectives of electrophysiological, optical, and ionic methods [170].…”

“…For the ion sensing of nitrate, ion-selective electrodes were chosen to modify the gate in order to enhance sensitivity, and a high sensitivity of 2.2 µA dec −1 was obtained. Furthermore, regulations for measurement conditions and device configuration have been reported for the realization of multimodal neuromorphic [171]. As shown in figure 8(c), Wang et al implanted a crystalline-amorphous channel (PTBT-p) of OECT that can be selectively doped in the volatile and nonvolatile modes [72].…”

Organic electrochemical transistors (OECTs) exhibit significant potential for applications in healthcare and human-machine interfaces, due to their tunable synthesis, facile deposition, and excellent biocompatibility. Expanding OECTs to the flexible devices will significantly facilitate stable contact with the skin and enable more possible bioelectronic applications. In this work, we summarize the device physics of flexible OECTs, aiming to offer a foundational understanding and guidelines for material selection and device architecture. Particular attention is paid to the advanced manufacturing approaches, including photolithography and printing techniques, which establish a robust foundation for the commercialization and large-scale fabrication. And abundantly demonstrated examples ranging from biosensors, artificial synapses/neurons, to bioinspired nervous systems are summarized to highlight the considerable prospects of smart healthcare. In the end, the challenges and opportunities are proposed for flexible OECTs. The purpose of this review is not only to elaborate on the basic design principles of flexible OECTs, but also to act as a roadmap for further exploration of wearable OECTs in advanced bio-applications.
