There is a need for an accurate end-of-life indicator for packaged food (meat, seafood, dairy
food etc.) beyond a simple “best use by” date on the food package. In this work, we propose …

In this paper, a fiber optic sensor for adulteration detection in petrol and diesel by kerosene
is proposed and demonstrated experimentally. The sensor consists of a multimode fiber with …

We review progress in the development of photonic platforms for detecting gases. Unlike
sensors based on conventional refractive and diffractive optics, photonic sensors detect …

Gas-coupled acoustic techniques show advantageous capability in analyzing gas mixtures.
It is still a challenge to identify the intrinsic characteristics of gas compositions from the …

Capsule endoscopy is a good method of gastric cancer diagnosis that has some advantages
over conventional endoscopy, such as providing reliable results without substantial …

This paper presents an improved piezoelectric sensor fabricated using reduced graphene
oxide (rGO)-filled polydimethylsiloxane (PDMS) elastomer composite that is able to sense …

For tactile sensors to become useful technology, the required features should be flexibility,
durability, and its sensitivity to physical contact. Conductive elastomer nanocomposites are …
