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.

Maintaining Sterility Assurance Level in Medical Device Design

To avoid costly interruptions later on, sterility assurance should be placed at the forefront of the design process.

A medical device undergoing design and classified as sterile will be confronted with various obstacles, not the least of which is how to determine and maintain its proposed Sterility Assurance Level (SAL) as it approaches its ultimate goal: delivery to market.

Electrocardiography (ECG) Necklace

Wearable monitoring system uses an ultra-low-power application-specific integrated circuit and a beat-to-beat detection algorithm to measure cardiac activity.

Integrated wearable monitoring systems based on body area networks (BANs) enable continuous, reliable, and long-term monitoring of physio- and biological signals on the move, leading to wearable health solutions for next-generation healthcare, wellness, and lifestyle. An electrocardiography (ECG) necklace has been developed to target the simultaneous monitoring of cardiac and physical activity in everyday life situations.

Utilizing Machine Vision Engines for Advanced Quality Control and Object Detection

Advanced object and feature recognition eliminates the need for physical probing or fixed sensors.

Incorporating machine vision engines into an OEM system with automated handling provides a wide range of benefits to the manufacturer. Machine vision engines are self-contained vision systems that include the optics, lighting, image sensor, electronics, and software to enable standalone “intelligent” decision-making using vision software. Machine vision engines are also much more compact than traditional industrial machine vision systems, which makes them more appropriate for integration into OEM systems with limited space.

Experimental Walking Assist Device With Body Weight Support System

This technology is designed for users who, though capable of walking on their own, would benefit from a reduction of load on their leg muscles and joints.

An experimental walking assist device has been developed to help support body weight and reduce the load on the user’s legs while walking, going up and down stairs, and in a semi-crouching position. The device reduces the load on leg muscles and joints (in the hip, knees, and ankles) by supporting a portion of the person’s body weight. It features a simple structure consisting of seat, frame, and shoes, and the user can put it on by simply wearing the shoes and lifting the seat into position. Moreover, a mechanism that directs the assisting force toward the user’s center of gravity and the ability to control the assist force in concert with the movement of the legs make it possible for the device to provide natural assistance in various postures and motions.

Epiretinal Prosthesis Surgically Implanted in the Eye

A miniature video camera housed in a pair of glasses captures a scene and relays the information to a receiver in the implant.

In a healthy eye, the photoreceptors (rods and cones) on the retina convert light into tiny electrochemical impulses that are sent through the optic nerve and into the brain, where they are decoded into images. If the photoreceptors no longer function correctly — due to conditions such as retinitis pigmentosa — the first step in this process is disrupted, and the visual system cannot transform light into images.

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.

Die Extrusion Technology for Medical Tubing Applications

Patent-pending process would allow 1000-plus layers from a single extruder.

Although the concept of nanotechnology (controlling matter on an atomic scale) dates back to 1959, it is only now becoming more commercially realized. It has the potential to challenge the way all products are extruded in almost every type of medical tubular or related industrial product applications.
