摘要: The utilization of organic devices as pressure-sensing elements in artificial intelligence and healthcare applications represents a fascinating opportunity for the next-generation electronic products. To satisfy critical requirements these promising applications, low-cost construction large-area ultra-sensitive pressure with outstanding flexibility is highly desired. Here we present flexible suspended gate thin-film transistors (SGOTFTs) model platform that enables detection. More importantly, unique device geometry SGOTFTs allows fine-tuning their sensitivity by gate. An unprecedented 192 kPa(-1), low limit-of-detection <0.5 Pa short response time 10 ms were successfully realized, allowing real-time detection acoustic waves. These excellent sensing properties SGOTFTs, together advantages facile fabrication versatility detecting various signals, make powerful strategy spatial mapping practical applications.
