Developments in flexible electronics have adopted various approaches which enhanced the applicability of human–machine interface fields. Recently, microstructural integration and hybrid functional materials were designed for realizing human somatosensory. Nonetheless, designing tactile sensors with smart structures using facile low-cost fabrication processes remains challenging. Furthermore, re...

Abstract Flow sensors play a critical role in monitoring flow parameters, including rate, velocity, direction, and rotation frequency. In this paper, inspired by biological hair cells the human vestibular system, an innovative sensor is developed based on polyvinyl alcohol (PVA) hydrogel nanocomposites with maze‐like network of vertically grown graphene nanosheets (VGNs). The VGNs/PVA absorbs c...

Biosensors based on microcantilevers have become a promising tool for directly detecting biomolecular interactions with great accuracy. Microcantilevers translate molecular recognition of biomolecules into nanomechanical motion that is commonly coupled to an optical or piezoresistive read-out detector system. Biosensors based on cantilevers are a good example of how nanotechnology and biotechno...

This paper describes the design, implementation and evaluation of a user-verification system for a smart gun, which is based on grip-pattern recognition. An existing pressure sensor consisting of an array of 44 × 44 piezoresistive elements has been used. An interface has been developed to acquire pressure images from the sensor. The values of the pixels in the pressure-pattern images are used a...
