Self-Charging Power Cell for Small Devices

A hybrid power cell uses a new technique for electrical charge conversion and storage. Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.

Medicine Delivery Device With Integrated Sterilization and Detection

This automated medicine delivery device would ensure that patients receive medication on schedule and at the right dosage level. Sterile delivery devices can be created by integrating a medicine delivery instrument with surfaces that are coated with germicidal and anti-fouling material. This requires that a large surface-area template be developed within a constrained volume to ensure good contact between the delivered medicine and the germicidal material. Both of these can be integrated using JPL-developed silicon nanotip or cryo-etch black silicon technologies with atomic layer deposition (ALD) coating of specific germicidal layers.

Less-Invasive Ventricular Assist Device for Late-Stage Heart Failure

First full-support mini cardiac pump FDA approved as bridge to cardiac transplantation. The first full-support, miniaturized ventricular assist device designed to be placed in the pericardial space, was approved by the FDA in late November. HeartWare International, Inc., Framingham, MA, an innovator of less invasive, miniaturized circulatory support technologies to treat advanced heart failure, said that its Ventricular Assist System was approved as a bridge to cardiac transplantation in patients who are at risk of death from refractory end-stage left ventricular heart failure.

Integrating Electrical Systems into 3D Mechanical Models

Real-time integration of 2D schematics and 3D models allows mechanical and electrical teams to better collaborate and deliver more accurate designs. Product development teams are under increasing pressure to engineer more complex products that combine numerous electrical systems within a single design, including visual interfaces, power systems, logic controllers, complex wiring and harnesses. Simplifying the design of these electro-mechanical systems using intelligent design tools, and a shared, comprehensive parts database, medical device designers are able to achieve significant cost savings. These savings are multiplied when this electrical design work is done in perfect synchronization with the mechanical and industrial design teams using a shared data model.

Paralympian ‘Catapults’ to a Silver Medal

A new type of carbon fiber running foot helped propel an American sprinter to a medal at the London Paralympic Games. At London’s Paralympic Games in September, USA track and field star Richard Browne took the silver medal in the highly anticipated 100-meter race for below-the-knee amputees. The 21-year-old was the first athlete to train with and compete with the Catapult® Running Foot from his sponsor Freedom Innovations, LLC, Irvine, CA, at a Paralympic Games.

Wideband Single-Crystal Transducer for Bone Characterization

These transducers have uses in medical ultrasound imaging and room-temperature ultrasonic flow meters. The microgravity conditions of space travel result in unique physiological demands on the human body. In particular, the absence of the continual mechanical stresses on the skeletal system that are present on Earth cause the bones to decalcify. Trabecular structure decreases in thickness and increases in spacing, resulting in decreased bone strength and increased risk of injury. Thus, monitoring bone health is a high priority for long-term space travel. A single probe covering all frequency bands of interest would be ideal for such measurements, and this would also minimize storage space and eliminate the complexity of integrating multiple probes.
