biosensor

(bī′ō-sĕn′sər, -sôr)
n.
1. A device that detects, records, and transmits information regarding a physiological change or process.
2. A device that uses biological materials, such as enzymes, to monitor the presence of various chemicals in a substance.

biosensor

(1) A sensor which collects data on a biologic or physiologic process—e.g., blood pressure, temperature, etc.
(2) A biomolecule or system—e.g., enzyme, receptor, antibody, organelle or cell—coupled to a microelectronic system or optical probe to enable rapid, accurate, low-level detection of substances in body fluids, water and air. Biosensors have been used to measure glucose, creatinine, ethanol, gamma globulin, lidocaine, nerve gases, penicillin, sodium ions, testosterone, theophylline, vitamin B12, and O2.

biosensor

(bī′ō-sen″sor″) [ bio- + sensor]
1. A device that senses and analyzes biological information, including temperature, heart rate, blood pressure, or the chemical composition of body fluids.
2. A device that incorporates some biologic agent (e.g. an enzyme) as a part of its sensing capability.

biosensor

a biological material such as an ENZYME, an ANTIBODY, a MICROORGANISM or other biological system, coupled to an appropriate transducing system, which act together to monitor a specific biochemical reaction and convert it into a measurable electrical signal. Biosensors may be used in health care, for example to measure specific METABOLITES in the body, and in the monitoring of pollutants in the environment. The enzyme glucose oxidase is used in the biosensor for monitoring GLUCOSE levels in the blood.

Transformation of physical movements of data glove into the virtual reality
Designed for accurate control and navigation in VR/AR environments, the BeBop Data Gloves are available to OEMs in 5, 10, and 14 sensor versions.
BeBop Sensors-designed Marcel Modular Data Gloves are available exclusively for OEMs.
("Hacking" here involves special equipment -- visors, data gloves, etc.--to visualize all of the world's interconnected computer data.
No wire-laden data gloves. A system in which a live person's video image unobtrusively feeds a "magic mirror" that interprets that person's silhouette and gestures in real-time, three-dimensional space.
It attempts to replace the physical world with a computer-generated one, using devices such as head-mounted display goggles and data gloves. The result is very useful for purposes such as visualization and simulation, but of course, the artifical world is much simpler than the real world; it has lower resolution, leaves out details, and is limited in its behavior and extent.
This feature is a big leap toward using such data gloves in common daily living.
In addition, devices like 6 DOF trackers, voice command or data gloves offer the possibility to interact with more natural gestures than the mouse and keyboard input of workstations.
Various interaction tools are used: a Trivisio Head Mounted Displays (HMD) stereo video see-through for visual output, an optical tracker system for spatial tracking of user hand position and orientation; data gloves for fingers gesture recognition and voice recognition for input commands (Figure 1).
The system can work with various 3-D input and output devices such as stereo projection screens, CAVEs, tracking systems, or data gloves.
As input devices 3D tracking is provided for designers head and both hands, and two data gloves with electrical contact on fingertips.
