This paper addresses the development of a wireless sensor system array for the detection and identification of bioterrorism agents and hazardous vapors and other gases with a realistic goal of "stick and forget sensing" especially attractive to homeland security needs. New and improved sensors are needed for many security applications with fast, reliable and sensitive detection and identification. Some of the most important tools in today's national security are biological and chemical agents' detection and identification. These devices need to be small and fast so that they can easily detect and identify any traces of hazardous materials. Biosensors are analytical devices which use biological interactions to provide either qualitative or quantitative results.Due to its ability to manipulate and organize matter and structures from atomic up to molecular scales, the nanotechnology is widely viewed as the most significant technological frontier which has to be explored in many areas including physical, chemical, electrical and biological sciences. Design and successful development of devices of the size of few nm to couple of hundreds of nm, nanotechnology has been heralded as most powerful technology as ever seen before. This has lead to the development of better materials, highly sensitive sensing systems and wide verity of nano-devices.This sensor array is based on Multi-walled Carbon Nanotube (MWCNT) as sensing element, which is synthesized and chemically bonded with different polymers for sensing different biological agents and gases. An array of these sensing elements with integrated ChemFET is connected to a low power wireless system for the real-time detection and identification. We have successfully demonstrated the detection and identification of various gases and chemicals using wireless setup.

The design of a novel feedback sensor system with wireless implantable polymer MEMS sensors for detecting and wirelessly transmitting physiological data that can be used for the diagnosis and treatment of various neurological disorders, such as Parkinson's disease, epilepsy, head injury, stroke, hydrocephalus, changes in pressure, patient movements, and tremors is presented in this paper. The sensor system includes MEMS gyroscopes, accelerometers, and pressure sensors. This feedback sensor system focuses on the development and integration of implantable systems with various wireless sensors for medical applications, particularly for the Parkinson's disease. It is easy to integrate and modify the sensor network feed back system for other neurological disorders mentioned above.The monitoring and control of tremor in Parkinson's disease can be simulated on a skeleton via wireless telemetry system communicating with electroactive polymer actuator, and microsensors attached to the skeleton hand and legs. Upon sensing any abnormal motor activity which represent the characteristic rhythmic motion of a typical Parkinson's (PD) patient, these sensors will generate necessary control pulses which will be transmitted to a hat sensor system on the skeleton head. Tiny inductively coupled antennas attached to the hat sensor system can receive these control pulses, demodulate and deliver it to actuate the parts of the skeleton to control the abnormal motor activity. This feedback sensor system can further monitor and control depending on the amplitude of the abnormal motor activity.This microsystem offers cost effective means of monitoring and controlling of neurological disorders in real PD patients. Also, this network system offers a remote monitoring of the patients conditions without visiting doctors office or hospitals. The data can be monitored using PDA and can be accessed using internet (or cell phone). Cellular phone technology will allow a health care worker to be automatically notified if monitoring indicates an emergency situation. The main advantage of such system is that it can effectively monitor large number of patients at the same time, which helps to compensate the present shortage of health care workers.

“…Wearable sensors to monitor motor functions include multi-axis accelerometers [2], [3]; combination of accelerometers and gyroscopes and electromyographic sensors [4]. Wearable sensors to monitor the physiological signals including temperature and biopotentials [6]- [9] have also been developed. Clinical evaluations proved that a combination of multiple sensors allow to estimate the kinematics of movement with reliability.…”

Wearable health monitoring systems have recently attracted widespread interest for their application in long term patient monitoring. Wireless wearable technology enables continuous observation of patients while they perform their normal everyday activities. This involves the development of flexible and conformable sensors that could be easily integrated to the smart fabrics. Carbon nanotubes are found to be one of the ideal candidate materials for the design of multifunctional e-textiles because of their capability to change conductance based on any mechanical deformation as well as surface functionalization. This paper presents the development and characterization of a carbon nanotube (CNT)-polymer nanocomposite flexible strain sensor for wearable health monitoring applications. These strain sensors can be used to measure the respiration rhythm which is a vital signal required in health monitoring. A number of strain sensor prototypes with different CNT compositions have been fabricated and their characteristics for both static as well as dynamic strain have been measured.
