  • Publication number: 20160128597
    Abstract: 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.

  • Publication number: 20140058243
    Abstract: 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. The encapsulation member wraps the conductive substrate, the conductive springs and the probes but reveals a portion of each probe. The revealed probes contact skin of a testee for biomedical measurement. The device and method of the present invention can reduce the cost in mass-production. The biosensor electrode device will be a mainstream instrument in biomedical measurement.

  • Patent number: 8543179
    Abstract: 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.

  • Publication number: 20130242077
    Abstract: 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.

  • Patent number: 8406841
    Abstract: 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.

  • Patent number: 8285355
    Abstract: 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.
