Thin-Film-Transistor (TFT) technology has been the key technology for liquid crystal displays (LCD) for thepast 30 years. LCDs are composed on a high density of pixel array. Each pixel is able to become transparent or opaque according to the voltage applied to it. The voltage applied to the pixel array is controlled by a transistor (TFT) array, and is transmitted to an array of transparent micro-electrodes.

The bottom part of LCDs, which contains the TFT array and the microelectrodes, has a structure which is of great interest for electrical sensing and studies of biological entities: it is transparent, with a wide and dense array of microelectrodes (Multi-Electrode-Array) which can be controlled individually. Our group is investigating the usage of this technology for applications as wide as cells manipulation, neurons stimulation and excitation, culture monitoring and biomolecule sensing.

Agnès Tixier Mita biography

She received her PhD in Microelectronics, in 1998, at the Universityof Lille I in France, and in collaboration with STMicroelectronics at Agrate Brianza in Italy, in the field of simulation of silicon technology.
Then she joined the UMI2820 LIMMS-CNRS / IIS, at the University of Tokyo, as a post-doctoral fellow, then as an assistant researcher, from 1999 to 2007, during which she developed her expertise in the field of microsystems for biological cells applications. Since 2010, she has been associate professor at the Research Center for Advanced Science and Technology (RCAST), the University of Tokyo.

Her current research interest includes sensors arrays with integrated electronics for cells manipulation, stimulation and sensing and for biomolecules sensing. In particular her group is a pioneer in using Thin-Film-Transistors technology to develop advanced Multi-Electrodes-Arrays devices for biological applications. Since April 2018, she has been involved in the JSPS-CNRS Bilateral project, entitled “PARIS: PARallel Integrated micro-System for High Frequency Action-Based Non-Invasive Multi-Modal Cell Analyses”, in collaboration with Prof. Bruno Le Pioufle at ENS Paris-Saclay, and Prof. Mita at VDEC, The University of Tokyo
