Thermoelectric devices have become efficient enough—and battery technology has improved enough—to finally allow electronics to replace the ice pack.

That’s what Alex Aguiar, a founder of RecoverX, told me. He says the company’s portable hot/cold wrap is deisgned for general athletic recovery. But, he says, they are also good enough to replace the post-surgical ice machine. If you’ve never had one in your house, trust me, this would be a really good thing: those machines are expensive, unwieldly, and you go through a ridiculous number of bags of ice, some of which you will accidentally dump on your living room rug.

The thermoelectric wraps, introduced at the Highway1 accelerator’s Demo Day in San Francisco on Wednesday, can be controlled by an app for precise hot and cold temperatures and time cycles. The company is beta testing the system with the San Francisco 49ers (American football), the San Jose Earthquakes (everybody else’s football), the Stanford University Athletic Department, and others. Aguiar expects it will ship in 2018 for US $250 to $300.

Asad Madni and the Life-Saving Sensor

In 1992, Asad M. Madni sat at the helm of BEI Sensors and Controls, overseeing a product line that included a variety of sensor and inertial-navigation devices, but its customers were less varied—mainly, the aerospace and defense electronics industries.

And he had a problem.

The Cold War had ended, crashing the U.S. defense industry. And business wasn’t going to come back anytime soon. BEI needed to identify and capture new customers—and quickly.
