Cambridge-Nanjing Forum 2025 Highlights Global Advances in Sleep Health and InnovationThe Cambridge Nanjing Forum 2025, 'Sleep Health and Clinical Monitoring and Treatment'was successfully held in Nanjing, spotlighting the pressing global public health issue of sleep disorders under this year’s World Sleep Day theme: “Healthy Sleep, A Priority for …

Our annual summer barbecue took place on August 12th, 2025. Staff, students, and invited guests spent a delightful afternoon enjoying good food and great company by the River Cam, in the scenic setting of Darwin College. Many thanks to everyone who came along and helped make the day memorable.

Tactile Augmentation of Material Classification via Imperceptible On‑Skin Triboelectricity CollectionHarnessing intrinsic triboelectric signals from human skin holds promise for enhancing tactile perception. However, collecting these signals without disrupting normal skin functions and convoluting motion artifacts remains challenging. Additionally,…

Electrically Tunable Fano Resonances in Liquid Crystal-based Dynamic Metasurface at Telecommunication WavelengthsDielectric metasurface has become a versatile platform for light manipulation. Due to its subwavelength feature size, the metasurface can induce optical resonances with tailored characteristics, such as Fano resonance with asymmetric lin…

Phase Flicker Induced Sharpness Deterioration of Holographic Images in LCoSPhase flicker in LCoS devices can decrease the effective phase modulation resolution by introducing overlapped phase oscillation between adjacent modulated grey levels, thus degrading the performance of LCoS devices in various applications. Nevertheless, the effect of phase …

LC Diffractive Optical Elements with High PB Phase Accuracy for Holographic DisplaysDiffractive optical elements (DOE) are important light manipulating components in modern imaging and display scenarios. However, the weight of the bulk material of traditional DOEs becomes more and more critical in novel optical systems. Meanwhile, the fabrication o…

Adaptive Contrast Enhancement in Computer-Generated Holography Using Nonlinear OptimizationThis study introduces an advanced nonlinear exponential merit function to enhance the contrast and dynamic range of computer-generated holography (CGH). By integrating adaptive energy redistribution into the Gerchberg–Saxton (GS) algorithm, the method selecti…

We CPDS group had the pleasure of hosting Prof. Li Zhang, a renowned clinical neurologist, and the Academic Director of the Sleep Medicine Centre at Nanjing Brain Hospital, for a visit to the University of Cambridge. Prof. Zhang brings over 20 years of experience in clinical research, with a particular focus on Parkinson’s disease and sleep disorde…

Professor Daping Chu has been elected as a 2025 Fellow of Optica, in recognition of his seminal contributions to display devices and his broader impact on industrial applications. Optica Fellows are selected based on several factors, including outstanding contributions to research, business, education, engineering, and service to Optica and the com…

A start-up pioneering nanophotonic lens technology for images that are always in focus has secured $5.3 million to bring the technology to market. AllFocal Optics is co-founded by Professor Daping Chu and CPDS alumni Dr Pawan Shrestha and Dr Xin Chang.  AllFocal Optics’ technology is built on 10 years of research and development in the Centre for P…

We hosted our annual dinner on December 9th, 2024, where CPDS staff, student members, and esteemed guests gathered to enjoy a delightful meal in the exquisite surroundings of Corpus Christie's College.

Professor Chu is co-author on a new paper in Science Advances which describes a multi-receptor sensing system that could be used to boost the sensing capabilities of robotic, haptic and prosthetic systems. Their bionic multi-receptor skin design incorporates tele-perception to enhance human perception and cognition beyond conventional noncontact se…
