Due to increasing demand for edge AI, the data amount from sensing devices for data processing needs to mitigated. To meet this requirement, the development of sensors inspired from the human sensory organs are of great interest. Human sensory systems are often based on sensory receptors connected with afferent neurons in which synaptic plasticity plays an important role in pre-processing of sensory signals. Through intelligent functions in human sensory organs, the signals are relayed to the brain and are further processed for perception, memory and control of motor neurons. Here are the lists of topics which are currently being investigated in our group. Design and fabrication of various field-effect transistor sensors with intrinsic synaptic functions mimicking mechanoreceptors, chemoreceptors and photoreceptors in human somatosensory systems. Development of neuromorphic engineering approaches employing machine learning for intelligent sensory perception. Wearable microfluidics-integrated biosensor patches for immunodetection of biomarkers in capillary blood or interstitial fluid. For this purpose, we are investigating the various nanostructured materials and biosensors. Here are the detailed topics related to biosensors. The main themes related to the biosensor-integrated platforms, the following topics are being investigated. Currently, our group is associated with AMSE (Department of Advanced Materials Science and Engineering), SAIHST (Samsung Advanced Institute of Health Sciences and Technology), newly developed interdisciplinary research institute initiated by the School of Medicine, College of Engineering, College of Information and Communication Engineering at SKKU, and SAINT (SKKU Advanced Institute of Nano Technology), an interdisciplinary research institute
