Crystalline semiconductors such as silicon can catch photons and convert their energy into electron flows. New research shows that a little stretching could give one of silicon's lesser-known cousins its own place in the sun.
Nature loves crystals. Salt, snowflakes and quartz are three examples of crystals – materials characterized by the lattice-like arrangement of their atoms and molecules.
Industry loves crystals, too. Electronics are based on a special family of crystals known as semiconductors, most famously silicon.
To make semiconductors useful, engineers must tweak their crystalline lattice in subtle ways to start and stop the flow of electrons.
Semiconductor engineers must know precisely how much energy it takes to move electrons in a crystal lattice.

A material inspired by the unique physics of geckos' fingertips could allow robotic hands to grip nearly any type of object without applying excessive pressure.
A promising new adhesive material was born out of a scrap.
David Christensen, a mechanical engineering graduate student at Stanford, was trimming a piece of adhesive modeled after the grippy fingers of geckos and noticed that the thin scrap seemed particularly grippy. He shared this observation with his colleague Elliot Hawkes, who laminated a piece of non-stretchable, but very flexible, film to the back of the scrap. They found that the combination greatly magnified the grip and allowed some surprising properties.

Students and faculty organized this inaugural Mechanical Engineering Conference to showcase the breadth of interdisciplinary research by the ME community.
Could we create 3D models of the brain so accurate that surgeons could use them to plan operations? Build space probes that hop over the surfaces of low-gravity comets and asteroids? Or develop micro-devices that would train lab-grown muscle cells to patch damaged hearts?
These were just three among the more than one hundred projects that were showcased at a recent conference designed to give students and faculty a chance to get a sense of the broad range of interdisciplinary initiatives being pursued by members of Stanford's mechanical engineering community.

In an interdisciplinary blend of engineering and medicine, Pruitt seeks to detect and measure the minute forces generated by living cells.
Associate Professor Beth Pruitt has been elected a fellow of the American Society of Mechanical Engineering (ASME) for work that includes a focus on creating micro-electrical systems (MEMS) to detect the minute forces that cells exert upon one another as they carry out the basic mechanics of life.

A team led by mechanical engineer David Lentink has identified the design qualities that make bird wings famously efficient over a wide range of flight styles. The research could lead to improved aircraft design.
It has taken more than a million fine samples of aerodynamic force and airflow combined to determine what makes a hummingbird's wings so adept at hovering.
The team led by David Lentink, an assistant professor of mechanical engineering at Stanford, believes that the results could have significant impacts in both aerodynamic research and in advancing bio-inspired designs of drones and other aircraft.
