There is provided herein, a method for adjusting a VAD device parameters using a wearable device placed on the patient's hand, the method includes the steps of acquiring a set of signals from sensors in the wearable device, computing at least one quality metric, and adjusting at least one VAD operational parameter so as to optimize at least the one quality metric.

Method and system for ventricular assistive device adjustment using a wearable device

A novel and useful pressure sensor array incorporating sensor elements constructed from electrically conductive film as a substrate. Examples of commercially available electrically conductive (i.e. piezoresistive) film include Velostat and Linqstat. A wearable device is described incorporating an array of pressure sensors with flexible properties and a biocompatible material interface between the sensor elements and a user's skin. The pressure sensor array uses the electrically conductive film as a substrate and places a pair of conductors in a suitable configuration to form individual sensor elements. The sensor elements detect the change in resistance of the electrically conductive film when pressure is applied thereto. The sensor elements may be implemented in an interdigitated or opposing configuration. The sensor array also comprises a mechanical interface on top of the sensor elements for transferring or focusing the applied pressure to the electrically conductive film.

Blood pressure measurement system using force resistive sensor array

A system and method for blood pressure signal acquisition using a pressure sensor array. A solution is provided for a non-inflatable, non-invasive, continuous blood pressure waveform and blood pressure acquisition system. The system is operative to combine signals from various sensing elements where the less accurate sensor elements are calibrated utilizing the more accurate sensor elements. Blood pressure measurements are acquired using very sensitive pressure sensors that detect slight pressure changes through the skin, which are sampled and processed to yield a blood pressure signal, which is processed to yield actual systolic and diastolic continuous and or intermittent blood pressure readings. By sampling and detecting the signal in each of the sensors, the sensor that is best placed on the target artery is found and the signals from that sensor is used to weight the signals from other sensors based on signal quality. The sensor array is placed approximately on the target artery making it highly likely that more than one element will acquire signal from the artery. Combining a plurality of such correlated signals with uncorrelated noise yields a signal to noise enhancement and more accurate blood pressure readings.
