Title: Odor sensorInventors: Mitachi Seiko (JP); Matsunaga Toshio (JP)Patent number: US2007151324Publication date: July 5, 2007
The present invention provides a biomimetic odor sensor that utilizes neither an oxide semiconductor nor a quartz oscillator, is hardly affected by the atmospheric moisture, simple in structure, inexpensive in production cost, fast in reaction rate, of a wet type, and provided with the condition close to the condition of the nasal mucosa of the human olfactus organ. The sensor according to the present invention includes a mixed material in which beta-carotene and a reducing agent to prevent the oxidation of the beta-carotene are dispersed in a viscous liquid, and a cathode electrode and an anode electrode are disposed so as to be in contact with the mixed material.
Title: Method and apparatus for use of thermally switching proteins in sensing and detecting devicesInventors: Brott Lawrence L (US); Naik Rajesh R (US); Stone Morley O (US); Carter Daniel C (US)Patent number: US2007295907Publication date: December 27, 2007
An apparatus and method for detecting infrared radiation is provided which comprises a temperature-sensing helical coiled-coil protein such as TIpA, CC1, collagen or myosin, incorporated into an electrically conductive film or gel deposited onto an electrically conductive medium, means for recording changes in conductivity or resistance of the conductive film or gel caused by the presence of infrared radiation and its effect on the thermal-sensing protein, and means to analyze the changes in conductivity or resistance in the conductive film caused thereby so as to determine if infrared radiation is present.; By virtue of the present invention, a “biomimetic” infrared sensor is provided which can integrate a recombinantly produced thermally sensitive protein in a conductive polymer matrix, such as a film or gel, and provide a low-cost, lightweight, conformable, and disposable infrared detecting device having high sensitivity and excellent dynamic range.
Title: Biomimetic tactile sensorApplicant: Alfred E Mann Inst Biomed Eng (US); Loeb Gerald E (US); Johansson Roland (SE)Patent number: WO2007126854Publication date: November 8, 2007
Disclosed is a tactile sensory system consisting of set of sensors that work by measuring impedance among plurality of electrodes. The electrodes are deployed on a substantially rigid structure that is protected form the direct contact with external objects by overlying deformable structures. These mechanical structures have similarities to the biological relationships among the distal phalanx, overlying finger pulp and covering skin and nail. Signal information is extracted form these sensors that is related to canonical physical representations used to describe stimuli to be sensed.
Title: Robot hand biomimetic finger flexible contact sensor arrayApplicant: Hefei Inst Of Matter Science C (CN)Patent number: CN100999079Publication date: July 18, 2007
The present invention relates to a robot hand claw bionic finger surface flexible contact sensor array. It can simulate sensory neuron structure of human hand. It is characterized by that it utilizes the combination of microtype pressure sensor and microtype flexible air bag to form the invented bionic finger surface flexible contact sensor. On the sensor base plate several microtype pressure sensors are set, on every microtype pressure sensor the microtype flexible air bag is fixed and can be used for covering said microtype pressure senor so as to obtain the invented robot hand claw bionic finger surface flexible contact sensor array.
Title: Sensor of species including toxins and chemical warfare agentsApplicant: Massachusetts Inst Technology (US); Swager Timothy M (US); Thomas Iii Samuel W (US); Venkatesan Koushik (US)Patent number: WO2008136805Publication date: November 13, 2008
The present invention generally relates to emissive materials, devices, and related methods. In some cases, the present invention provides sensors and methods for the determination of analytes, wherein the analytes may be determined by monitoring, for example, a change in an optical signal of an emissive material upon exposure to an analyte. The analyte and the emissive material may interact via a chemical reaction, such as an oxidative addition reaction, or other chemical, biochemical or biological interaction (e.g. recognition), to form a new emissive species. In some cases, the present invention may be useful in the detection of a wide variety of analytes, such as toxins, chemical warfare agents, and explosives. The present invention also provides emissive compounds, and related methods, including metal complexes that are capable of interacting with an analyte to produce a change in the emission of the compound. Some advantages of the present invention include the determination of analytes with high specificity and sensitivity and the ability to fabricate simplified and highly portable devices.
Title: Methodology and apparatus for the detection of biological substancesApplicant: Biowarn LLC (US); Oleynik Vladislav A (US)Patent number: WO2008133719Publication date: November 6, 2008
A methodology and an apparatus for the detection of biological substances employing the integration of multiple functions and units designed into and implemented in a sensor unit and system. The deployment of a set of sensor units as a group results in a distributed detecting, discriminating, and alerting system and network. Distribution of the sensor units facilitates real-time, in the field detection of different biological substances such as viruses, bacteria, spores, allergens, and other toxins that can be suspended in multiple media such as air, liquid, and blood. Besides detection/sensing, the system and individual sensor units perform: data acquisition, data development, data storage, statistical analysis, and data transmission.
Title: Biopolymer sensor and method of manufacturing the sameApplicant: Kaplan David (US); Omenetto Fiorenzo (US); Lawrence Brian (US); Cronin-Golumb Mark (US); Georgakoudi Irene (US)Patent number: WO2008127402Publication date: October 23, 2008
