| Term | Definition |
|---|---|
| Bandwidth | 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). |
