MEASURING PROPERTIES OF AN ANATOMICAL BODY

摘要

A medical device includes a sensor that is configured to measure a property of an outer layer of an anatomical body surface. The sensor includes a source probe configured stimulate a local surface of the outer layer of an anatomic al body surface. The sensor also includes a detector configured to measure a response of the outer layer resulting from the source probe stimulation. A controller coupled to the source probe and the sensor drives the source prob e using a tailored stochastic sequence and determines the property of the oute r layer using the measured response received from the detector. The sensor can be used with medical devices, such as drug delivery devices including microneedle transport devices and needleless injection devices.
