Pistons are muscling up

Researchers have developed a new way to design pistons that replaces their conventional rigid elements with a mechanism using compressible structures inside a membrane made of soft materials. The resulting ‘tension pistons’ generate more than three times the force of comparable conventional pistons, eliminate much of the friction, and at low pressures are up to 40 percent more energy efficient.
