Biosensor coated with electroactive polymer layer demonstrating bending behavior

Номер: US20120004522A1
Автор: Jang-Hyun Youn, Seon-Jeong Kim, Sun Ill Kim
Принадлежит: Industry University Cooperation Foundation IUCF HYU

Disclosed is a biosensor coated with an electroactive polymer layer demonstrating a bending behavior, more specifically a biosensor including an electroactive polymer layer coated on the surface of a bioreceptor and an electrode connected to the electroactive polymer layer. When an electrical stimulation is applied to the electrode, the electroactive polymer layer shows a bending behavior and thus the surface of the bioreceptor can be exposed to an analyte to allow a concentration analysis of the analyte. When used as an implantable biosensor, the disclosed biosensor may have a substantially increased life span since the bioreceptor can be selectively exposed to the analyte.

A device for gathering data has first and second electrodes. The first electrode is coupled to a surface of interest, and the second electrode is coupled to “everything else” or “the air”. The first electrode is shielded from the second, and from most sources of parasitic capacitance, by a shield that is driven by an active driver that drives the shield to track, and ideally to match, the instantaneous potential of the electrode. The second electrode is likewise shielded in a similar way from most sources of parasitic capacitance. These shields likewise help to limit the extent to which RFI from the device electronics couples with either of the electrodes. In this way the sensing device achieves a markedly better signal-to-noise ratio at frequency bands of interest.

A system includes a sensor device having a body configured to be inserted into an airway of a patient and one or more sensors mounted in or on the body. The one or more sensors are configured to collect sensor data associated with the airway of the patient. The system also includes a signal analyzer configured to analyze the sensor data. The one or more sensors could include one or more microphones. The signal analyzer could identify volume and/or pitch characteristics of the sensor data, perform pattern recognition to identify one or more patterns using the volume and/or pitch characteristics, and use the one or more patterns to identify a type, a location, and/or a degree of airway obstruction. This could be done, for instance, to determine if the patient suffers from obstructive sleep apnea or other condition that affects his or her airway.

Physiological data acquisition utilizing vibrational identification

Номер: US20120146795A1

Принадлежит: Gubbi Umesh Renukanand, Kenneth Margon

The present invention utilizes an accelerometer (included within a wireless physiology monitoring device or as part of a separate device such as, but not limited to a smartphone, e.g., iPhone, or other mobile device) to link a patient with a separate medical data acquisition device such as a weight scale or a blood pressure monitor in order to collect and transmit a range of medical data associated with the user. The medical data acquisition device includes a vibration source for emitting a vibration at a predetermined or random frequency. When the acquisition device is activated, a vibration is transmitted from the through the patient and is detected by the accelerometer. The accelerometer then measures the particular frequency of vibration and transmits this information to a centralized monitoring unit (CMU). Based on the measured frequency, the CMU is able to know that the same patient wearing/holding the device is also the same patient using the data acquisition device. The vibration source may revolve through a number of predetermined frequencies (as determined on its own or instructed via the CMU) or simply generate a random frequency.

Advances in our understanding of the cellular mechanisms underlying skeletal regeneration have not been effectively translated in vivo treatment because non-invasive monitoring of bone fracture healing is limited to imaging technology (i.e., for example, x-rays) that cannot be quantified and are subjectively interpreted. The method disclosed herein assesses rates of hip fracture healing using a strain gauge device implanted into a standard orthopedic implant. It has been demonstrated that such a device can measure differences between intact and partially osteotomized fracture models (p<0.05) and that the device can distinguish between stable and unstable fracture patterns in completely osteotomized models across a physiologic range of loads. Such devices are compatible with in vivo bone fracture healing methods, wherein the device is placed onto an orthopedic implant and the strain data is transmitted on a real time basis, thereby providing a non-invasive quantification of bone fracture repair rates.

A system and method is described for a catheter guidance system which allows an operator to use a mapping catheter to specify tissue target locations for the automatic guidance of a second therapeutic catheter. The operator places a mapping catheter at a desired location, and commands the catheter guidance system by either selecting a point on that catheter or one of the catheter electrode electrocardiograms. The operator may target the selected dynamic location, or tissue contact beyond that location on a specific side of the mapping catheter.
