Biomedical Sensors- Advancing Medical and Biotechnology
Introduction to Sensors
Sensors are regarded as small, tiny and intelligent devices that are used to measure physical variable like Temperature, Humidity, Gas, Velocity, Flow Rate, pressure and many others. According to American National Standards Institute, “A Sensor is defined as device which provides a usable output in response to a specified measure.”
A Sensor acquires a physical quantity and converts it into a signal suitable for processing e.g. Optical, Electrical, Mechanical. In today’s world, the words “Sensor” and “Transducer” are used in abundance especially in the description of measurement systems. The word “Sensor” is derived from entire meaning ‘to perceive’ and “Transducer” …show more content…

On the basis of Sensor Placement: Strip Sensors, Wearable Sensors, Implantable Sensors, Invasive/Non-Invasive sensors, Ingestible Sensors.
Biomedical Sensors Kits Available in Market for Patients Diagnostics
Biosensor is a kind of device which senses biomaterial and its concentration, and which converts the biosignal into electrical signal.
Special features of biosensor are the following:
1. Biological active material immobilized is used as catalyst, and expensive reagents could be repeatedly used to detect same biological parameters.
2. Biosensor has intensive specificity. Biomaterial only senses definitive ingredient and it is not affected by colour and concentration of measured material.
3. Biosensor could quickly analyse the result of the measurand.
4. Biosensor’s accuracy is very high; which relative error could reach one percent.
5. Biosensor’s analysing system is very simple.
6. The cost of biosensor is very low.

A. DMI
DMI stands for DNA Medical Institute. It is a portable, compact device that uses a single drop of blood to perform hundreds of clinical lab tests, telling patients with gold-standard accuracy whether they have anything from the common cold to Ebola. DMI has a wide reach, focusing on global health, emergency and critical care, and space

    For the heat inactivation, two sets of 11 tubes were set up. The indicated amounts of buffer, water, and ONPG listed in table 10 were added to each tube. In addition, the control enzyme (0.1ml) was added to each tube of the control set and the same amount of heated enzyme was added to each tube of the heated set. The absorbance readings were taken and recorded in table 10. Finally, two Lineweaver-Burk plots were created. The plot for the heated set is represented by graph 10 and graph 11 represents the control set. The Km and the Vmax for the heated set and the control set were determined.

  • What Are The Pros And Cons Of Health Information Exchange (HIE?

    1479 Words  | 3 Pages

    Health Information Exchange (HIE) was introduced by President Bush in 2004 (Kruse, Regier & Rheinboldt, 2014) so it is not a new concept. HIE is instrumental in gaining overall population health as it can lead to a reduction in healthcare costs, increase patient safety, and increase health outcomes. Regional Health Information Organizations (RHIOs) are a conglomerate of healthcare providers and patients in a region that exchange healthcare information with the goal of delivering quality care to the individuals they serve. This paper will discuss the pros and cons of RHIOs, key challenges in gaining long term viability, and provide ways in which capital is raised to support HIE.

    The main purpose of EHRs is to mainly exchange health information electronically to help improve quality and safety for patients. Four pros of EHRs is to provide accurate and recent information of the patients, allow for quick access to the patient records, share the health information securely, and make patient records and notes legible. These four points are important and necessary because the goal overall is to improve public health. Patient information should always be updated and current. Health professionals need to easily have access to patient records to either update them or verify the information. Also, health professionals can now avoid any discrepancies with electronic records verses when records were completely on paper.

  • Pros And Cons Of Medical Error

    1703 Words  | 4 Pages

    Today, medical error has become a major and important challenge to health care systems across the globe. This is because medical errors often lead to harm that may also be non-repairable (Valiani et al. 540; Denham “Chasing Zero”). In 1999, the Institute of Medicine published a report that indicated that medical error in hospitals accounts for between 48,000 and 98,000 deaths annually (Swift et al. 78; Barger et al. 2441). As such, reducing the occurrence of medical errors has become an international concern. Poorolajal defines a medical error as “an act of omission or commission in planning or execution that contributes or could contribute to an unintended result.” (Poorolajal, et al. para 5 -10). In this case, it’s very important to acknowledge

    Included in this paper will be my attempt to discuss the advantages and disadvantages with patients and providers communicating via patient portals. First, What is a Patient Portal? 
Patient Portals are healthcare related online applications that allow patients to interact and communicate with healthcare providers, such as physicians and hospitals. (Wilkipedia) The portal allows you to see, recent doctors visit, discharge summaries, Medications, Immunizations, allergies, and Lab results. Through a patient portal, 
Providers can also send patients post visit instructions, post clinical summaries and lab results via an attachment. This works well if you only go to one set of physicians in a group, such as a hospital portal. Many of us have probably

    We as human beings utilize the five senses to process information about our surroundings. These senses help keep us safe. For example, we use our sense of touch to avoid picking up a hot pan, while our senses of smell and taste prevent us from cooking any rotten food in the pan. Our sense of sight allows us to see an oncoming train, while our sense of sound makes it possible to hear the train’s horn.

    Sensing is how we take in information from our surrounding world (Kroeger, Thuesen, & Rutledge, 2002). I believe that one can clearly see how being a sensor is beneficial for any member of the military. We rely on what we know, we make decisions based on intelligence, and very seldom do we conduct any kinds of operations without having facts to support us. This is typical for a sensor; acting on data, experience, and facts, rather than going into the unknown (Kroeger, Thuesen, & Rutledge, 2002).

  • Sensation And Senception: The Process Of Sensation And Perception

    742 Words  | 2 Pages

    Sensation refers to the process of sensing what is around us in our environment by using our five senses, which are touching, smell, taste, sound and sight. Sensation occurs when one or more of the various sense organs received a stimulus. By receiving the stimulus, it will cause a mental or physical response. It starts in the sensory receptor, which are specialized cells that convert the stimulus to an electric impulse which makes it ready for the brain to use this information and this is the passive process. After this process, the perception comes into play of the active process. Perception is the process that selects the information, organize it and interpret that information.
