A label-free RF MEMS-based biosensor is described for detecting biomarkers in a given environment. The biosensor is capable of sensing the presence of biomarkers by exploiting both its mechanical and electrical characteristics. In addition, the method employed for detecting mechanical deflections due to antigen-antibody binding uses a simple electrical circuitry which allows the sensor to be used at any location and time. Such a sensor, when placed in a matrix like structure allows for the detection of multiple biomarkers simultaneously.

A biodegradable, bio-compatible material is described for use in wireless biosensors for point-of-care applications. The biosensor made from this biomaterial is capable of sensing environmental effects and as well as presence of bio-logical entities in the environment of concern simultaneously. Such a sensor can be used for evaluating point-of-care environmental preparedness for a specific patient through continuous monitoring of patient health performance due to environmental exposure. A two-tier network architecture is established for real-time monitoring (static case) that also provides warning of accumulated exposure. Wavelet analysis can be used to identify anomalies in the sensed data to initiate a warning.

Wireless biosensor network for point of care preparedness for critical patients

Described herein is an energy harvesting device and a method for its fabrication for the harvesting of solar energy. Solar energy is absorbed using a photosensitive material which is coated upon a flexible membrane, which is suspended over a metal signal line of an RF MEMS structure. By controlling the discharge sequence the stored electrical charge can be transferred as high voltage pulses to an external load or rechargeable batteries. The output voltage can be adjusted by controlling the on/off frequency of operation of the switch.

Energy harvesting using RF MEMS

This invention relates to a novel wireless barcode MEMS canary which can be embedded in electronic systems and periodically monitored to measure degradation over a period of time. The material used to print the bars of the barcode is selected such that it is capable of changing one or more of its properties in response to a change in ambient conditions. Means are provided for reading out said change in properties such that when an interrogator is brought into proximity to the sensor, the change in properties can be detected. By establishing the relationship between the healthy state of the barcode and its degradation to that of the electronic system and the components, the residual life of the system can be established and preventive measures taken before failure.
