Optical beam deflection (OBD) is the most prevalent method for measuring cantilever deflections in atomic force microscopy (AFM), mainly due to its excellent noise performance. In contrast, piezoresistive strain-sensing techniques provide benefits over OBD in readout size and the ability to image in light-sensitive or opaque environments, but traditionally have worse noise performance. Miniatur...

An interfacing circuit for piezoresistive pressure sensors based on CMOS current conveyors is presented. The main advantages of the proposed interfacing circuit include the use of a single piezoresistor, the capability of offset compensation, and a versatile current-mode configuration, with current output and current or voltage input. Experimental tests confirm linear relation of output voltage...

Flexible stress sensor arrays, comprising multiple flexible units, enable accurate quantification and analysis of spatial distribution. Nevertheless, the current implementation arrays faces challenge excessive signal wires, resulting in reduced deformability, stability, reliability, increased costs. The primary obstacle lies electric amplitude modulation nature unit’s (e.g., resistance capacita...

Flexible and wearable sensors for human performance sensing have received increased attention, particularly for fitness, healthcare, sports, and military applications. In particular, the measurement of human vital signals provides rich datasets for assessing the subject’s physiological or psychological condition, which are directly linked to performance. Instead of using conventional, bulky, we...

This paper presents the development of an innovative measuring system devoted to the human movement analysis using smart textiles that are realized with electrically conductive elastomer composites (CEs). CEs show piezoresistive properties when a deformation is applied and in several applications CEs can be integrated into fabric or other flexible substrate as a strain sensor. Moreover, integra...
