Abstract: An integrated ion-sensitive probe is provided. In an example, an ion-sensitive probe can include a semiconductor substrate and a first passive electrode attached to the semiconductor substrate. The first passive electrode can be configured to contact a solution and to provide a first electrical voltage as function of a concentration of an ion within the solution. In certain examples, a passive reference electrode can be co-located on the semiconductor substrate. In some examples, processing electronics can be integrated on the semiconductor substrate.

Abstract: The disclosed technology generally relates to integrated circuit devices with wear out monitoring capability. An integrated circuit device includes a wear-out monitor device configured to record an indication of wear-out of a core circuit separated from the wear-out monitor device, wherein the indication is associated with localized diffusion of a diffusant within the wear-out monitor device in response to a wear-out stress that causes the wear-out of the core circuit.

Abstract: A blood oxygenation sensor is provided comprising: a first current-powered light source to produce light having a first wavelength; a second current-powered light source to produce light having a second wavelength; a light sensor to produce a current signal having a magnitude that is indicative of intensity of light incident upon it; a current level driver circuit that includes a current source configured to couple the current source to alternatively provide current to one of the first current-powered light source and the second light current-powered light source; a processor configured to predict times of occurrence of one or more first time intervals in which arterial volume at a tissue site is at one of a maximum and a minimum; wherein the processor is configured to control the current source, to provide a first pattern of higher power-dissipation current pulses to the first and second current-powered light sources during the first time intervals, and to provide a second pattern of lower power-dissipation current pulses to at least one of the first and second current-powered light sources during second time intervals.
