1. Functional Elastomer
Elastomer is the basic material of flexible stretch electronic devices, and it is one of the important research contents in the field of elastic electronics. The research group carried out in-depth research on the electrical properties, mechanical properties, interface stability, self-healing and degradable / recyclable properties of elastomer materials, including: exploring the modification of elastomers through molecular structure design and microstructure assembly of materials, breaking through the limitations of mechanical and chemical properties; adding nano functional materials to elastomers, endowing elastomers with electrical and mechanical properties Based on the optical and thermal properties, we will construct the functional elastomer based stretchable electronic devices, and carry out related application research to expand the application fields of elastic electrons.
2. Epidermal Electronics and HMI
Based on the composite of nano functional materials and bioelastomers, biosensors such as electroencephalogram (EEG), electromyography (EMG), electrocardiograph (ECG), sweat and blood glucose were constructed. The epidermal electron with self-adhesive function was prepared, which could continuously contact with skin surface or subcutaneous tissue, and collect human physiological signals and skin movement signals in real time. This direction focuses on flexible sensor arrays based on stretchable sensors, field-effect transistors and microneedle arrays, and integrates sensors and signal amplifiers for continuous health monitoring, mobile / remote diagnosis and treatment, and human-computer cooperation.
3.Electronic Skin and Tactile Intelligence
Skin is the largest organ of human body, which has the ability to sense a variety of external stimuli at the same time. Based on the bionic principle, the multi parameter flexible tactile sensing array is studied to realize the parallel sensing of positive pressure, shear force, soft hardness, roughness and sliding sense of the grasping object, which is the basis for the robot to complete accurate, stable, adaptive and dexterous operation tasks in unstructured environment. The research group intends to improve the tactile sensing ability of the manipulator to a level beyond that of the human hand in terms of sensitivity, resolution, response speed and measurement range, and further study the fusion method of multi parameter tactile information and intelligent decision-making algorithm, and develop a robot dexterous hand operating system based on tactile intelligence.
4.Photonic Skin and Visual-tactile Fusion
Taking advantage of the advantages of Applied Optics, this paper studies the robot photonic skin based on electroluminescence, force luminescence, grating and infrared technology, and carries out optical measurement on the contact pressure, surface morphology, temperature and other attributes of the operating object, so as to realize the robot tactile visualization. Furthermore, based on the advantage of tactile information of optical signal, the information fusion and intelligent decision algorithm of tactile and robot vision are studied, and the cross modal fusion sensing technology is developed to realize the robot autonomous dexterous operation.
5. Flexible Energy Devices
Compared with the heavy and rigid energy acquisition and conversion equipment, portable flexible and extensible energy devices will become an indispensable part of wearable electronics, skin electronics and intelligent robot industries. The research group focuses on nano friction power generation technology based on extensible polymers and new functional materials, which can efficiently collect environmental energy such as human motion energy, vibration energy and thermal energy, and apply them to self driving sensors. At the same time, energy storage technologies such as supercapacitor and thin-film battery matching with flexible and extensible energy acquisition devices are studied.
