Porphyrins and related macrocycles have been intensively exploited as sensing materials in
chemical sensors, since in these devices they mimic most of their biological functions, such …

Chemical analysis based on colour changes recorded with imaging devices is gaining
increasing interest. This is due to its several significant advantages, such as simplicity of …

With the advent of the 5G era and the rise of the Internet of Things, various sensors have
received unprecedented attention, especially wearable and stretchable sensors in the …

Developments in the emerging fields of smartphone chemical and biosensing have
dovetailed with increased interest in environmental and health monitoring for resource …

Wireless communication refers to data transfer in an unguided propagation medium through
wireless carriers such as visible light (VL) and radio frequency (RF). The rapidly growing …

Research on electronic healthcare (eHealth) systems has increased dramatically in recent
years. eHealth represents a significant example of the application of the Internet of Things …

One of the major challenges with a nitric oxide (NO) gas sensor is the development of a
facile and robust room temperature gas sensor for fast recovery and high response in an NO …

In this paper, we first present a single-input, multiple-output convolutional neural network
that can estimate both heart rate and respiration rate simultaneously by exploiting the …

Herein, we describe the development of a mask for electrochemical breath gas
measurement. The readout board, with dimensions of 16× 43× 12 mm, enables Bluetooth …

In the diagnosis of respiratory diseases, it is necessary to have a wearable device capable
of measuring the breathing rate. We propose a sensor based on the integration of a …
