Patent number: 9877673Abstract: Transdermal sampling and analysis device, method and system are provided for non-invasively and transdermally obtaining biological samples from a subject and determining levels of analytes of the obtained biological samples. The transdermal sampling and analysis device, method and system may cause disruption to the skin cells to create capillary-like channels from which biological samples may flow to the transdermal sampling and analysis device. The transdermal sampling and analysis device, method and system may collect the biological samples in a reservoir where the biological sample may chemically react with a biologically reactive element. A sensor may convert the produced electrons (ions) into measured electrical signals. The converted signals may be measured and the levels of an analyte may be determined based on the measured signals.Type: GrantFiled: November 11, 2011Date of Patent: January 30, 2018Assignee: CLINITECH, LLCInventors: John F. Currie, Joseph A. Marcanio, Joseph J. Vidalis, Sundar B. Nadarajan

Patent number: 5986291Abstract: The channel region of the FET device has a first portion adjacent the source which has a higher bandgap energy or a higher electron affinity than a remaining portion of the channel. A quasi-electric field in the channel near the source is intensified and as a result, accelerates charge carriers in the channel and increases switching speed. An infrared controlled FET device is also disclosed in which a low bandgap channel layer has a large bandgap layer deposited on it to result in a conduction band discontinuity at the junction between the large bandgap semiconductor layer and the low bandgap channel layer and a two-dimensional electron gas (2DEG) channel in the low bandgap channel layer so that photons reaching the 2DEG eject charges and allow conduction through the channel layer.Type: GrantFiled: October 12, 1993Date of Patent: November 16, 1999Assignee: La Corporation de L'ecole PolytechniqueInventors: John F.
