A sensor is a device that converts a physical parameter or an environmental characteristic (e.g., temperature, distance, speed, etc.) into a signal that can be digitally measured and processed to perform specific tasks. Mobile robots need sensors to measure properties of their environment, thus allowing for safe…

The cross-sensitivity of a gas sensor can be mitigated by installing a catalytic filter upstream. The objective of the filter is to convert interferents into species that interact weakly with the recognition element of the sensor. Mathematical models may be useful for optimizing the design parameters of the catalytic…

'Roozbeh Khodambash'] Abstract: In this study, we have proposed a new type of tactile sensor that is capable of detecting the stiffness of soft objects. The sensor consists of a brass cylinder with an axial bore. An iron core can easily move inside the bore. Three peripheral bobbins were machined in the cylinder around…

Cellular processes are carried out by many interacting genes and their study and optimization requires multiple levers by which they can be independently controlled. The most common method is via a genetically-encoded sensor that responds to a small molecule (an “inducible system”). However, these sensors are often…

The human immune system is a complex network of cells, tissues, and organs that work together to protect the body from harmful pathogens. Antibodies, also known as immunoglobulins (Ig), are small proteins that play a vital role in the immune system's defense mechanism. Among the five classes of immunoglobulins…

Electrochemical biosensors based on the combination of DHP, OG, AuNPs, and G6PD, used to determine the enzymatic activity of G6PD, showed optimal current intensity values close to pH 7.8 at room temperature. Square wave voltammetry was optimized and used to evaluate the responses of the biosensors during the enzymatic…

-Despite advances in a diversity of environments, snake robots are still far behind snakes in traversing complex 3-D terrain with large obstacles. This is due to a lack of understanding of how to control 3-D body bending to push against terrain features to generate and control propulsion. Biological studies suggested…

A gravimetric, MOF-based (MOF = metal-organic framework) sensor array functions by measuring the mass of gas adsorbed in an array of MOFs. Changes in the gas composition are expected to produce detectable changes in the mass of gas adsorbed in the MOFs. In practical settings, multiple components of the gas adsorb into…

Dissolved Oxygen (DO) quantification is an important measure of the overall health of a water system. Fluctuations from normal values can indicate the presence of contaminants, and predict further events, for example, fish deaths resulting from eutrophication. DO can vary due to a variety of environmental factors…
