Wearable health sensor systems are widely sought as a means for long-term, minimally invasive, portable, and low-cost sensing solutions. These systems have applications in both assessing human health and in identifying threats present in the environment. The key challenges limiting the development of these systems are determining suitable sensor metrics (how sensitive or how specific), sensor robustness, and ease of sensor fabrication. The hurdles are complicated by limits to size, weight, power, and cost. This research examines an innovative multimodal sensor design that leverages 1) commercial foundry capabilities, 2) mixed signal design, and 3) novel devices modalities (biological and non-biological) that offer unique strategies to overcome these barriers. Specifically, this project explores integration of low power physiological sensors based on electrochemical, impedance, temperature, pH, and light that include secure hardware encryption and microprocessors for signal processing on the same chip. The multimodal sensor-on-a-chip system will include power management and wireless transmission to enable remote data download.
