An Electro-Optical System with a Computation Model for Scanning Human Body

The invention describes an Electro-Optical instrument and a computational model for functional scanning of human body and recovering its chromophores (water, lipid, oxygenated hemoglobin, and deoxygenated hemoglobin). It is a low cost portable system that integrates frequency domain and continuous wave domain for real time spectroscopic imaging of human tissue.

Novel Vibration Force Sensor with Hepatic Feedback for Minimal Invasive Surgery

Minimally Invasive Surgery (MIS) in the form of laparoscopic surgery has dramatically increased in the last decade and has led to reduced access trauma in addition to providing significant benefits for the patient via better recovery times and cosmetics. Robotic Minimally Invasive Surgery (RMIS) has also increased in popularity. Both methods require haptic feedback (sense of touch) to be successful. Current haptic feedback methods for tele-operated surgical systems involve integrated force sensors that are difficult to miniaturize, non­sterilizable, non­versatile, delicate, and costly. Haptic feedback methods such as displacement sensors and resistive sensors have a variety of shortcomings. When force is applied to the structure, there is strain, thereby, causing the electrical resistance in the strain gauge to change. Both of these methods are not adaptable to the existing endowrist instruments, and require modifications to the endowrist. Moreover, these methods often involve a trade­off between its function in measuring the magnitude and direction of force and its cost in manufacturing; inventions involving these methods are composed of delicate and complex parts dramatically increasing the cost.

Novel Sensor to Transduce and Digitalize Temperature Utilizing Near-Zero-Power Levels

Temperature sensors are routinely found in devices used to monitor the environment, the human body, industrial equipment, and beyond. In many such applications, the energy available from batteries or the power available from energy harvesters is extremely limited, thus the power consumption of sensing should be minimized in order to maximize operational lifetime.

Novel Anti-Bacterial, Anti-Fungal Nanopillared Surface

Medical devices are susceptible to contamination by harmful microbes, such as bacteria and fungi, which form biofilms on device surfaces. These biofilms are often resistant to antibiotics and other current treatments, resulting in over 2 million people per year suffering from diseases related to these contaminating microbes. Death rates for many of these diseases are high, often exceeding 50%. Researchers at UCI have developed a novel anti-bacterial and anti-fungal biocomposite that incorporates a nanopillared surface structure that can be applied as a coating to medical devices.
