Microworm optode sensors limit particle diffusion to enable in vivo measurements

Microworm optode sensors limit particle diffusion to enable in vivo measurements.

There have been a variety of nanoparticles created for in vivo uses ranging from gene and drug delivery to tumor imaging and physiological monitoring. The use of nanoparticles to measure physiological conditions while being fluorescently addressed through the skin provides an ideal method toward minimally invasive health monitoring. Here we create unique particles that have all the necessary ph...

Particle Size Measurements Using Diffusion Broadening Spectroscopy

Weight Measurements by Using Simple Optical-Fiber Sensors (RESEARCH NOTE)

The use of different optical-fiber sensors for weighing measurements is Abstract described. By using three different mechanical stressing mechanisms, the operation of the fiber-to-fiber transducer systems are tested and the results are presented. Parameters such as sensitivity, hysteresis, resolution, and dynamic range are measured. A comparison of the results has shown that the sensor system m...

Smart Sensors Enable Smart Air Conditioning Control

In this study, mobile phones, wearable devices, temperature and human motion detectors are integrated as smart sensors for enabling smart air conditioning control. Smart sensors obtain feedback, especially occupants' information, from mobile phones and wearable devices placed on human body. The information can be used to adjust air conditioners in advance according to humans' intentions, in so-...

Topology Changes Enable Reaction-Diffusion to Generate Forms

This paper demonstrates some examples that show the ability of reaction-diffusion mechanism to code the curvature of forms of multi-cellular systems. The simulation model consists of two layers: the first generates reaction-diffusion waves and the second diffuses chemical substances. The results show that topology changes feedback information to the reaction-diffusion mechanism allowing the con...
