Brain Sensing Technology Provides Real-Time Diagnosis

Portable system identifies, assesses, and monitors cerebral abnormalities, including stroke, traumatic brain injury, and sports concussion.Every 21 seconds, someone suffers a serious brain injury, including stroke, trauma, or concussion. Until now, there has been no way to quickly and reliably diagnose these calamities.

Tear-Based Glucose Sensor for Diabetes Monitoring

Diabetic control typically requires daily monitoring of blood glucose levels. This involves finger pricking 2–10 times a day in order to obtain a sample for assay. Many find the finger prick tedious or painful and fall into noncompliance. Others may also dislike the assorted “paraphernalia” that must be carried around. Research into the “next-tech” for diabetes care has led many researchers to investigate tear glucose sensing as an alternative. As promising as many of these devices are, they are many years from market. Here the development of a near market tear glucose sensor is reported.

Biosensing Technology Offers Advanced Diagnostic Capabilities

An electronic biosensing platform, combining nanoelectronics and three-dimensional electronic system integration, could replace the conventional microplate.Electronic biosensing technology could someday displace the multi-welled microplate, long a standard tool in biomedical research and diagnostic laboratories. Essentially arrays of tiny test tubes, microplates have been used for decades to simultaneously test multiple samples for their responses to chemicals, living organisms, or antibodies. Fluorescence or color changes in labels associated with compounds on the plates can signal the presence of particular proteins or gene sequences.

Ultra-Miniature Image Sensor

A wafer-level camera operates at low power and may be customized for application needs, which include endoscopy, surgical robots, and 3D model generation.Minimally invasive surgery has increasingly required imaging devices to have the smallest possible dimensions but also deliver high-resolution vision capabilities. There has also been a rising demand for disposable medical devices. With these criteria in mind, in 2004, the first prototype of the NanEye sensor was created in the lab. The miniature 0.25 mm2 camera module measured 0.5 mm × 0.5 mm, with 140 × 140 pixels at a frame rate of 40 frames/second.

Repeatable, Low-Cost UV Assembly of Biosensors

UV spot curing system ensures greater accuracy for automated and manual manufacturing of biosensors.A biosensor is an analytical device that converts a biological response into an electrical signal. It is increasingly being used as a cost-effective diagnostic tool that offers the capability to render efficient, easy-to-use, and accurate diagnosis. While technological advances in biosensors are allowing this technology to cater to an extensive range of applications in a number of fields, such as industrial and environmental testing, the largest applications have been in the healthcare sector, including glucose detection, pregnancy testing, blood testing, breath analyzers, and cancer diagnosis.

Ultrasonic Echo Probe With Measurement of Contact Pressure Distribution

This probe can measure tissue inside living bodies non-invasively using a thin-film piezoelectric pressure sensor.This ultrasonic echo apparatus can measure tissue inside living bodies, non-invasively. The developed probe has a film-like piezoelectric sensor installed on the contact surface of an ordinary medical ultrasonic probe, and it can measure the contact pressure distribution between the probe and living bodies. Since it can measure, with an ultrasonic echo image, the deformation of living bodies when a probe is pressed against them dynamically, it can calculate the distribution of mechanical impedance within living bodies by using information on contact pressure at the contact surface.
