Background:

Flexible tactile sensors are crucial for health monitoring and human-machine interfaces.
Electrospun nanofiber mats offer comfort and breathability for wearable applications.

Purpose of the Study:

To develop a flexible, self-powered tactile sensor with enhanced piezoelectric properties.
To demonstrate its utility in wearable devices for tactile feedback and object manipulation.

Main Methods:

Fabrication of metal-free organic electrodes using electrospun thermoplastic polyurethane (PU) nanofibers decorated with multi-walled carbon nanotubes.
Utilization of an electrospun polyvinylidene fluoride-trifluoroethylene (PVDF-TrFE) mat as the piezoelectric layer, enhanced with barium titanate (BaTiO3) nanoparticles.
Assembly of a sandwich-structured sensor and testing its response to external forces.

Main Results:

The addition of BaTiO3 nanoparticles enhanced the piezoelectric performance of the PVDF-TrFE nanofiber mat by approximately 187%.
The tactile sensor demonstrated a near-linear relationship between applied force and electrical output.
An array of sensors attached to a glove successfully estimated the mass of a grasped object (water).

Conclusions:

The developed flexible, self-powered tactile sensor exhibits excellent flexibility, enhanced piezoelectric performance, and breathability.
It shows significant potential for applications in wearable robotics, prosthetics for tactile feedback, and advanced human-machine interfaces.
