Polyaniline-nanospines engineered nanofibrous membrane based piezoresistive sensor for high-performance electronic skins

This paper proposes a highly sensitive hybridized nanofibrous membrane-based pressure sensor to overcome the limitations of existing piezoresistive sensors. Polyaniline (PANI)-nanospines are uniformly deposited on hybrid hierarchical nanofibers, achieving high sensitivity over a broad pressure range, making it suitable for electronic skin (e-skin) applications.

• A new hybridized nanofibrous membrane-based pressure sensor.
• High sensitivity (179.1 kPa⁻¹) and a low detection limit (1.2 Pa).
• Linear response over a broad pressure range (0 - 50 kPa).
• High durability demonstrated over 10,000 cycles.

A pressure sensor was fabricated by uniformly depositing PANI-nanospines on a hybrid hierarchical nanofibrous membrane. The sensor's sensitivity, detection limit, linear working range, and durability were characterized.

The fabricated pressure sensor demonstrated high sensitivity, a low detection limit, and a wide linear pressure range with high durability. These results indicate its strong potential for applications in e-skins and wearable electronic devices.
