The range of frequencies over which the measurement system can
operate within a specified error range.
BAW
Bulk acoustic wave.
Bilayer lipid membrane (BLM)
The structure found in most biological membranes, in which two
layers of lipid molecules are so arranged that their hydrophobic
parts interpenetrate, whereas their hydrophilic parts form the two
surfaces of the bilayer.
Binary
Numbering system based on powers of 2 using only the digits 0 and
1, called "bits".
Biosensor
The term" biosensor" is a general designation that denotes either
a sensor to detect a biological substance or a sensor which
incorporates the use of biological molecules such as antibodies or
enzymes. Biosensors are a subcategory of chemical sensors.
Bipolar-junction transistor
Transistor with n-type and p-type semiconductors having
base-emitter and collector-base junctions.
Bit
see binary.
Body-centered cubic (BCC)
A common crystal structure found in some elemental metals. Within
the cubic unit cell, atoms are located at corner and cell center
positions.
Brazing
A metal joining technique that uses a molten filler metal alloy
having a melting temperature greater than about 425oC
(800oF).
Breakdown
Failure of a material resulting from an electrical overload. The
resulting damage may be in the form of thermal damage (melting or
burning) or electrical damage (loss of polarization in
piezoelectric materials).
