1. Flexible electronic skin

Electronic skin is made by plating silver on PI film which is similar to the flexibility of human skin to sense changes in external temperature, humidity and pressure. In temperature sensing, the resistance of Ag coated on the PI film changes with temperature and the temperature is detected. For humidity sensing, it detects humidity by forming a capacitance by parallel distribution of silver on the PI film. For pressure sensing, a flexible piezoresistive material made of graphite powder doped with PDMS, which has good compatibility with PI, is coated on PI film to produce a pressure sensor.

Technical innovation: in the flexible polyimide film by covering different shapes of silver to produce temperature, humidity, pressure and other sensors, so that the traditional hard sensor device into a flexible device, wearable, can sense the environmental temperature, humidity, pressure, etc., so that you can collect the sensory data of human skin. This flexible electronic skin can also replace the human skin will be relevant tactile information collected and transmitted back to the control side, it will be combined with the robotic arm can also make the robotic arm and human arm action is similar to the difference.

 

2. Development and application of seed-farming model based on ultrafine bubble technology.

1. Ultra-fine bubble technology
Ultra-fine bubble technology usually refers to the use of physics principles, the gas in the form of ultra-fine bubbles injected into the water body. The bubbles produced by this technology are generally less than 50μm in particle size, where 1~50μm bubbles are called micro-bubbles and bubbles less than 1μm are called nano-bubbles. Compared with ordinary bubbles, ultrafine bubbles have large specific surface area, high surface energy, good suspension stability, strong permeability and other characteristics, can be widely used in agriculture, forestry and fisheries, environmental protection, energy, medicine, food, building materials and other fields.

3. MEMS bioinformatics detection device based on non-diagonal giant magnetic impedance sensor

This project develops a bioinformatic detection device based on micromechanical non-diagonal giant magnetic impedance effect (GMI) technology. The non-diagonal GMI-based magnetic field sensor is fabricated using a micromechanical process to make it as small as a few tens of micrometers in size. At the same time, the resolution of the sensor is up to 300 pT (the geomagnetic field is about 50 million pT). The specific detection method is to combine organic polymers with inorganic nanoscale magnetic microspheres by biological method to form a magnetic microsphere with certain magnetic properties and special structure. These magnetic microspheres can be connected to antibodies, which in turn can be connected to the corresponding biological target through immune reaction, thus establishing a correspondence between the magnetic microspheres and the target. In this way, a micromechanical, non-diagonal giant magnetic impedance sensor can be used to measure the weak magnetic field changes caused by the microspheres, which can be used to confirm the presence and number of magnetic microspheres and characterize the presence and number of biological targets to be tested. The bioinformatic measurement device developed using this method can achieve rapid detection of biological targets while maintaining accuracy, and also miniaturize the device to make it portable.
