Abstract
The present invention relates to a piezoelectric biosensor comprising carbon nanotubes (CNTs), optionally combined with an amplification system, to a process for preparing the same and to an apparatus comprising said piezoelectric biosensor, in particular a medical device usable for monitoring a body parameter. A piezoresistive biosensor according to the invention comprises at least one micropattern of a composite mixture layered on a flexible support, said composite mixture comprising at least a flexible biocompatible polymer and carbon nanotubes (CNTs) and said at least one micropattern having a continuous rectangular shape.
