Research Projects

Cardiovascular disease (CVD) is a significant global health concern, and long-term monitoring is often necessary for individuals living with such conditions. Flexible and conformable sensors have been developed to monitor key physiological signs for CVD. Recent research focuses on technologies with smaller size, monolithic integration, and greater performance due to the demand for small, low-cost, and low power consumption products. Micro-electrical mechanical systems (MEMS) are a disruptive technology that can change both industrial and consumer products. A piezoelectric sensor based on MEMS technology is the best option for future biomedical sensor systems and low sound pressure level monitoring. Piezoelectric sensors are electronic instruments that measure sound and frequency levels for various purposes, such as tracking physiological and pathological states. MEMS-based sensors can more accurately identify the vibrational content of acoustic signals, allowing for more accurate representation of their characteristics. India, a major national business that manufactures and disperses biomedical applications, has a strong need for biomedical products. The proposed methodology aims to design and develop a piezoelectric MEMS sensor and its interface circuit for heart sound monitoring and related applications. The sensor will have several features, including MEMS technology for measuring low sound pressure levels, a highly sensitive and small-sized sensor with a separate interfacing circuit, a wide frequency range (10 Hz to 1.5 kHz), biocompatible material for healthcare use, and various piezoelectric materials used as Piezo layers for reliable and sensitive devices.
