Publication number: 20160128597Abstract: A thin planar biological sensor is provided, comprising at least one flexible electrode used for contacting a subject's skin and measuring biological signal. The flexible electrode is made of silicon-silver-based material, in which a ratio of silicon to silver-compound is about 7:3. A conductive plate is coupled to the flexible electrode. A buffer layer covers the conductive plate and the flexible electrode. A printed circuit board is used to receive the measured biological signal. By employing the novel proposed biological sensor, it is advantageous of measuring biological signals not only EEG signals but also ECG and EMG signals. Besides being thin, planar, flexible and non-allergy attributing a low cost to the proper fabrications makes the proposed sensor characterized with a potential for becoming an important tool of medical measurement.Type: ApplicationFiled: September 4, 2015Publication date: May 12, 2016Inventors: CHIN-TENG LIN, YI-HSIN YU, SHAO-WEI LU, LUN-DE LIAO

Publication number: 20140058243Abstract: A biosensor electrode device and a method for fabricating the same are disclosed. The biosensor electrode device comprises a conductive substrate; at least one conductive spring, at least one probe, and an encapsulation member. Two ends of the conductive spring respectively connect with the conductive substrate and the probe. The probe moves close to or far away from the substrate through the elastic deformation of the conductive spring.

Patent number: 8543179Abstract: A biomedical sensor device includes a light source, a probe array, and a photo detector. The light source is configured for emitting infrared radiation. The probe array is contacted to a user's skin to detect an electric wave signal transmitted through the probe array from the skin. The probe array includes a substrate and a plurality of probes mounted on the substrate, wherein the substrate and the probes are non-opaque so that the infrared radiation may be transmitted through the probe array into the skin. The photo detector is configured to detect an infrared signal by measuring the infrared radiation absorption by the skin.Type: GrantFiled: June 8, 2009Date of Patent: September 24, 2013Assignee: National Chiao Tung UniversityInventors: Yu-Han Chen, Lun-De Liao, Paul C.-P.

Publication number: 20130242077Abstract: An image control system able to detect electrooculography (EOG) is provided. The system detects EOG signals of a user through an electrooculography detection device and wirelessly transmits the signals to an external signal processing device. The external signal processing device calculates a position the user is staring at according to the signal received and presents on a display unit a sharp image of the position. Thereby, the present invention makes the user enjoy the feeling of watching real objects although the user is viewing a photo presented on the display in fact. Thus is optimized the visional quality in viewing photos.Type: ApplicationFiled: July 5, 2012Publication date: September 19, 2013Inventors: Chin-Teng LIN, Zhong-Ho Chen, Lun-De Liao, I-Jan Wang

Patent number: 8406841Abstract: A dry electrode for biomedical signal measuring sensor includes a conductive sponge, a conductive fabric, and a thin metal film. The conductive fabric covers the whole conductive sponge, and the thin metal film is disposed on one face of the conductive fabric opposite to the conductive sponge. When using the dry electrode in measuring biomedical signal, it is not necessary to apply a conductive gel on a patient's skin, at where the biomedical signal is to be measured. Without the need of applying the conductive gel, the dry electrode is readily for measuring biomedical signal at any time and can be conveniently used in measuring signal over a long period of time without the problem of an attenuated signal due to gradually becoming dried conductive gel.Type: GrantFiled: December 6, 2010Date of Patent: March 26, 2013Assignee: National Chiao Tung UniversityInventors: Chin-Teng Lin, Lun-De Liao

Patent number: 8285355Abstract: A biomedical electric wave sensor includes a base, a central pole, a dry electrode, a case, and a plurality of ribs. When the central pole lowers down, the ribs radiate and expand outward to push aside the hair of a subject, and the dry electrode exposes from the case and contacts the skin of the subject to measure a physiological electric wave signal from the subject. The present invention may overcome the intervention problem caused by hair and achieve the measurement of biomedical electric wave signal.Type: GrantFiled: May 12, 2010Date of Patent: October 9, 2012Assignee: National Chiao Tung UniversityInventors: Yu-Han Chen, Paul C.-P.
