SCIVAX announced the development of the world's smallest PPG (PhotoPlethysmoGraphy) sensor head. This innovation to be showcased at the "Touch Taiwan" exhibition in Taipei, Taiwan, from April 16 to 18, 2025. PPG sensors can be used to measure a variety of physiological parameters, including the heart rate, heart rate variability, blood pressure, blood oxygen. PhotoPlethysmoGraphy (plethysmography) is a method of measuring pulse waves, which are volumetric changes in blood vessels caused by the beating of the heart, from slight tonal changes that occur in the skin.
The newly developed PPG sensor head boasts a mounting area of approximately 1 square millimeter, a mere 1/10th the size of conventional devices. Additionally, the device thickness is halved, marking a significant reduction in size. This miniaturization enables the sensor to be installed in previously inaccessible narrow spaces, broadening its application potential.
By deploying multiple PPG sensor heads in an array, the device can achieve more precise sensing. This capability allows for accurate blood flow measurement even in confined spaces, making it ideal for beauty applications, home healthcare, and nursing. The integration of SCIVAX's nano-imprinted lens technology with TSLC’s advanced packaging technology has been pivotal in achieving this innovation.

"We are thrilled to introduce this groundbreaking PPG sensor head, which represents a significant leap forward in vital sensing technology," said Satoru Tanaka, President of SCIVAX Corporation. "Our collaboration with TSLC has enabled us to push the boundaries of miniaturization and precision, opening up new possibilities for applications in healthcare and beyond."
The global PPG biosensors market is experiencing rapid growth, driven by the increasing demand for wearable health monitoring devices and the rising prevalence of chronic diseases. The market, valued at USD 423.1 million in 2022, is projected to reach USD 1.2 billion by 2032. This significant growth is fueled by advancements in sensor technology and the integration of PPG sensors into smaller, wearable medical devices. The introduction of the world's smallest PPG sensor head by SCIVAX and TSLC is poised to further accelerate this market expansion, offering enhanced precision and cost-effectiveness that can drive broader adoption across various sectors, including healthcare, sports, and personal wellness.
