Improving Medical Devices with Force Sensing Technology

This white paper explores the exciting new trend toward designing smart medical devices that provide critical force feedback to eliminate guesswork, improve outcomes, and increase consistency. Technical topics covered include the unique advantages of force sensing resistor technology over traditional technologies such as strain gauges and load cells. These advantages include simpler electronics, wider dynamic range, ease of integration, and lower cost. The white paper highlights how thin and flexible sensors have enhanced a wide range of medical device applications by providing force feedback and making the products smart.

New Actuators and Motors Key to Improved Robot Responders

Sandia National Laboratories is developing technology that will dramatically improve the endurance of legged robots, helping them operate for long periods while performing the types of locomotion most relevant to disaster response scenarios. One area of focus is battery life – an important concern in the usefulness of robots for emergency response. The first robot Sandia is developing is a fully functional research platform that allows developers to try different joint-level mechanisms that function like elbows and knees to quantify how much energy is used. The key to the testing is Sandia’s novel, energy-efficient actuators, which move the robots’ joints. The actuation system uses efficient, brushless DC motors with very high torque-to-weight ratios, very efficient low-ratio transmissions, and specially designed passive mechanisms customized for each joint to ensure energy efficiency. Electric motors are particularly inefficient when providing large torques at low to a crouching robot. A simple support element, such as a spring, would provide torque, reducing the load on the motor. Source:

Launch System Engine Gets a New “Brain”

The engine controller unit on the RS-25 – formerly known as the space shuttle main engine – helped propel all of the space shuttle missions to space. It allows communication between the vehicle and the engine, relaying commands to the engine and transmitting data back to the vehicle. The controller also provides closed-loop management of the engine by regulating the thrust and fuel mixture ratio while monitoring the engine's health and status. The engine controller unit needed a "refresh" to provide the capability necessary for four RS-25 engines to power the core stage of NASA's new rocket, the Space Launch System (SLS), to deep space. An engineering model RS-25 controller is being tweaked and tested at NASA Marshall. At one of the center's test facilities, engineers are simulating the RS-25 in flight, using real engine actuators, sensors, connectors, and harnesses. A second engineering model controller and RS-25 engine also recently were installed on a test stand at NASA's Stennis Space Center. Pending final preparation and activation work, the engine test series is anticipated to begin this year. Source:

Detecting Extraterrestrial Life Through Motion

Looking for life on other planets is not straightforward. It usually relies on chemical detection, which might be limited or even completely irrelevant to alien biology. On the other hand, motion is a trait of all life, and can be used to identify microorganisms without any need of chemical foreknowledge. Scientists have now developed an extremely sensitive yet simple motion detector that uses a nano-sized cantilever to detect motion. The idea comes from the technology behind an atomic force microscope, uses a cantilever to produce pictures of the atoms on a surface. The cantilever scans the surface like the needle of a record player, and its up-and-down movement is read by a laser to produce an image. The new motion sensor works the same way, but a sample is attached on the cantilever itself. If the sample is alive, it will inevitably move in some way,. That motion also moves the much smaller and sensitive cantilever, and it is captured by the readout laser as series of vibrations. The signal is taken as a sign of life. Source:

Remediation and Prevention of Moisture in Electronics

Receiving product complaints and returns may be your first indication that there is a problem with moisture in your electronic product. Moisture in sealed electronics may result in shorting, attenuation problems, mirror and lens fogging, intermittent functionality, and catastrophic failure. The experience your customer has with your product directly affects your brand integrity, which in turn affects sales and profits. Taking steps to correct a moisture issue or prevent it early on in the design stages can help you make large strides in reclaiming or protecting your brand position.
