"Currently, most methods used for testing the sugar content in fruits require damaging the fruit's tissue. However, Crimson Vision, a startup supported by Hong Kong Baptist University, has developed a multi-mode optical sensor that can detect the sugar content of fruits without damaging the fruit's inner structure. The device uses a combination of near-infrared and visible light spectroscopy to quickly and non-invasively analyze the sugar content of fruits in just a few seconds. Additionally, the company has proposed an Internet of Things (IoT) solution to address fruit traceability issues using QR codes. The device recently won a gold award at the Geneva International Invention Exhibition."

“The multi-mode photodetector (PD) responds in near infrared (NIR) and visible light ranges, generating either NIR or visible light photocurrents. The bias-switchable spectral response PD can obtain quality information via photocurrents, and it offers an attractive quality control option for applications in environmental pollution, bio, medical, agricultural, automotive, fishery, food, wellness and security monitoring, detection and imaging. ”
