Abstract
A micro sensor device for measuring a concentration of a substance within a sample comprises an integrated sensor head having a tip portion adapted to be inserted into a sample, a light source for emitting a beam of light into and through the tip portion with the tip portion capable of interacting with a substance within a sample to produce a reflected pattern of light, and a detector for receiving the reflected pattern of light, and a body portion coupled to the integrated sensor head, the body portion comprising a processor operatively connected to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.
Claims18
A micro sensor device for measuring a concentration of a substance within a sample comprising:
- at least one integrated sensor head module having a tip portion being sized and adapted to be inserted into a sample through intercellular gaps or through a cell membrane, said module including a light source for emitting a beam of light into and through the tip portion, said tip portion being capable of transmitting light and having an exterior surface treated to interact with a substance within a sample to produce a reflected pattern of light, said module further including a detector for receiving the reflected pattern of light;
- and
- a body portion coupled to the integrated sensor head module, the body portion comprising a processor operatively coupled to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.
A micro sensor device for measuring a concentration of a substance within a sample comprising:
- a first integrated sensor head module having a tip portion being sized and adapted to be inserted into a sample through intercellular gaps or through a cell membrane;
- a second integrated sensor head module coupled to the first integrated sensor head module, the second integrated sensor head module comprising a light source for emitting a beam of light into and through the first integrated sensor head module and the tip portion being capable of transmitting light and having an exterior surface treated to interact with a substance within a sample to produce a reflected pattern of light, and a detector for receiving the reflected pattern of light;
- and
- a body portion coupled to the second integrated sensor head module, the body portion comprising a processor operatively coupled to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.
A micro sensor device for measuring a concentration of at least two different substances within a sample comprising:
- an integrated sensor head module having a tip portion being sized and adapted to be inserted into a sample through intercellular gaps or through a cell membrane, said module including a light source for emitting a beam of light into and through the tip portion, said tip portion being capable of transmitting light and having an exterior surface treated to interact with at least two different substances within a sample to produce a first pattern of reflected light and a second pattern of reflected light, said module further including a first detector for receiving the first pattern of reflected light and a second detector for receiving the second pattern of reflected light;
- and
- a body portion coupled to the integrated sensor head module, the body portion comprising a processor operatively coupled to the light source and the detector, the processor for controlling the light source for emitting the beam of light, for receiving the pattern of reflected light from the detector, and for processing the reflected pattern of light to determine the concentration of a substance within a sample.
