Today's microprocessors and Systems-on-Chip are thermally limited. Many, therefore, employ dynamic thermal management (DTM) to maximize performance under a reliability constraint. Accurate thermal monitoring is critical as temperature underestimation can hurt reliability by excessively aging devices and overestimation can hurt performance by unnecessarily throttling computing components. Placing temperature...
This paper presents a novel multimodal CMOS based biosensor consisting of integrated capacitive and thermal sensors for Lab-on-Chip applications. A new capacitive sensor is also proposed which converts the capacitance changes to frequency by using a current-controlled oscillator. This sensor works based on charge based capacitance measurement (CBCM) technique. Its operation in current mode helps this...
In this paper, an low power CMOS temperature sensor for implantable applications is implemented in a 0.18 μm CMOS process. Sensors for implantable devices must have sub-μW power consumption to avoid tissue overheating. Thus, this temperature sensor employs subthreshold MOS transistors as the sensing element to reduce power consumption and enable minimum supply voltage. Temperature is converted to...
Printed electronics have gained increased interest in recent years, and printed sensors, which promise mechanically flexible multifunctional electronics over large areas, are raising remarkable attention. Numerous low cost printing technologies have been developed on different flexible/stretchable substrates including textiles. This paper presents a brief summary of various passive sensors (humidity,...
Temperature management of the food supply-chain is important for ensuring compliance and the quality of perishable products like vaccines and fish. While conventional strategies have relied on using monitors attached to packaging containers, self-powered time-temperature monitoring is attractive because the technology can be embedded with passive RFID tags and can be integrated with every food or...
The objective of this project is to create a novel device to monitor and report back with comprehensive physiological status and alerts of hazards encountered by the firefighter. The device is a band-aid like device that would be attached to the firefighter's skin positioned on the upper arm. The device would monitor the firefighter's physiological health including heart rate and blood oxygen level,...
Runtime hardware Trojan detection techniques are required in third party IP based SoCs as a last line of defense. Traditional techniques rely on golden data model or exotic signal processing techniques such as utilizing Choas theory or machine learning. Due to cumbersome implementation of such techniques, it is highly impractical to embed them on the hardware, which is a requirement in some mission...
