Pressure sensing based on high-sensitivity and fast-response photonic devices is essential for various transient and dynamic processes in diverse fields. Therefore, a miniaturized device being capable ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

Objective: Photo-plethysmography (PPG) sensors are often used to detect pulse transit time (PTT) for potential cuff-less blood pressure (BP) measurement. It is known that the contact pressure (CP) of ...

In this work, capacitively sensed squeeze-film pressure sensors are implemented in a silicon-based fabrication platform to facilitate multi-sensor integration.
