  • Mechanical Metamaterials and Vibration Control Technology

    Mechanical metamaterials are man-made structures with counterintuitive mechanical properties that originate in the geometry of their unit cell instead of the properties of each component. They can be considered a counterpart to the well-known family of optical or acoustics metamaterial. Mechanical Metamaterials include auxetic (negative Poisson’s ratio) metamaterials, metamaterials with vanishing shear modulus, such as pentamode structures, metamaterials with negative compressibility, singularly nonlinear materials, and topological metamaterial.

  • Smart Soft Materials and Bio-Inspired Actuators

    Smart soft materials can perceive and deal with internal and external information (such as force, heat, light, electromagnetic, chemical, radiation, etc.) to make active or passive response. They mainly include electroactive polymers, shape memory polymers, liquid crystals, gels and so on. Different from the traditional hard material, the intelligent soft material has the advantages of controllable large deformation, high degree of freedom and so on.

  • Flexible Electronics and Tactile Feedback

    Flexible electronic sensing systems, which usually contains stimulus responsive material and stretchable polymers, are one of the key technologies in the next generation of smart personal electronics. With this technique, physical, chemical, biological, and environmental status of the human body could be monitored with high efficiency and minimum discomfort. So far, various types of wearable electronic sensors, including flexible tactile sensors, wearable image sensor array, biological and chemical sensor, temperature sensors, and multifunctional integrated sensing systems have been developed.

  • Energy Harvesting by Smart Materials

    Highly flexible and ultra-thin elastomeric membranes are used as capacitors. These membranes are installed in streams, where the constant deformation and relaxation of the elastomeric body converts mechanical kinetic energy from the flow of water directly into electricity.
