Advanced Bioinspired Organic Sensors for Future‐Oriented Intelligent Applications

Abstract

Bioinspired organic sensors with excellent flexibility, biocompatibility, sensing performance, and self-adaptability have attracted considerable attention due to their fundamental role in next-generation intelligent sensory systems with simultaneous sensing and processing functions, such as advanced robots, disease diagnosis, Internet of Things, human-robot interaction systems, and beyond. The design of advanced bioinspired organic sensors requires a deep understanding of the interplay between the unique material property, sensing mechanism as well as intelligent functionality. Here, the recent progress of bioinspired organic sensors for artificial perceptron covering visual, tactile, and other bionic sensors from the view of materials, sensing mechanisms, and functionality, is summarized. Furthermore, the intelligent applications of bioinspired organic sensors, including associative learning, information security, electronic skin, and integrated artificial sensory systems, are presented. Finally, the potential challenges and prospects of bioinspired organic sensors are discussed, providing a promising avenue toward advanced bioinspired organic sensors for future-oriented intelligent applications.

Brain‐Inspired Organic Electronics: Merging Neuromorphic Computing and Bioelectronics Using Conductive Polymers

“…They are essential for perception, movement control and understanding risk assessment. [176] Receptors specialized on the detection of neurotransmitter are generally found inside the synapse, but synaptic adaptation is an attribute that translates to receptors for other types of stimuli as well. [177] Embedding synaptic features such as spike-timing dependent plasticity (STDP), paired pulse facilitation (PPF), or long-term plasticity into artificial sensing systems can aid in filtering out repetitive or disorganized data.…”

“…[177] Embedding synaptic features such as spike-timing dependent plasticity (STDP), paired pulse facilitation (PPF), or long-term plasticity into artificial sensing systems can aid in filtering out repetitive or disorganized data. Recent literature [176,178,179] offers comprehensive reviews on (organic) synaptic sensing technologies. Here, we highlight specific examples to emphasize critical features of organic artificial synapses (Figure 5c,f).…”
