Tunable Photocapacitive Optical Radiation Sensor Enabled Radio Transmitter and Applications Thereof

RPI ID: 2013-048-401

Innovation Summary:
This innovation presents an optical sensor that integrates a photosensitive material and impedance-modulating element with a wireless transmission system. It is capable of converting incident light into an electrical impedance response, which is then translated into a wireless signal. The system eliminates the need for batteries or wired power sources, enabling truly autonomous sensor nodes. Because it can be fabricated using scalable and large-area manufacturing processes, it is well-suited for deployment in distributed sensing environments. The technology supports multi-modal sensing, potentially capturing both light intensity and wavelength information. It allows seamless integration into smart lighting systems, security installations, and medical diagnostics platforms. Its minimal energy requirements make it an ideal candidate for IoT and edge sensing networks.

Challenges / Opportunities:
Traditional optical sensors often require separate power supplies and data acquisition systems, limiting their usability in large networks or remote areas. This invention replaces those dependencies with a self-powered, wireless sensor platform. It addresses the growing need for distributed, autonomous, low-maintenance sensor systems. By combining capacitive sensing with wireless output, it creates a versatile platform for smart infrastructure. Opportunities abound in areas like smart cities, precision agriculture, and biomedicine.

Key Benefits / Advantages:
✔ Energy-autonomous wireless sensing
✔ Scalable and flexible form factor
