A highly flexible and sensitive piezoresistive sensor based on MXene with greatly changed interlayer distances

Abstract: Since the successful synthesis of the first MXenes, application developments of this new family of two-dimensional materials on energy storage, electromagnetic interference shielding, transparent conductive electrodes and field-effect transistors, and other applications have been widely reported. However, no one has found or used the basic characteristics of greatly changed interlayer distances of MXene under an external pressure for a real application. Here we report a highly flexible and sensitive piezoresis… Show more

“…Its compressible sheets‐laminated structure is a crucial factor to change the MXene internal resistance and the conductivity of the MXenes. Nevertheless, the present MXene based pressure sensor quickly reached the deformation limit of MXenes in limited space of the 2D plane under the external stimulation, which considerably restricts the sensor's performance. Additionally, most of the previous studies just focused on the sensitivity or limit of pressure detection or other indicators, while few of them could perceive the multifunctional microforce within one simple structure, like sounds, touch, and motion recognition.…”

“…There are more than 70 known M n +1 AX n or MAX phases, indicating that numerous MXenes of varying compositions could be explored . MXene's rich chemistries and unique 2D morphologies have sparked intense interest in the exploitation of MXenes for energy storage, catalysis, conductive reinforcement additives, and chemical sensing . As a typical case in MXene family, Ti 3 C 2 T x MXene has metallic conductivity and shows amazing electrochemical activity, which could be highly beneficial in sensor development for various diagnostic purposes .…”
