Electronics replace the old-fashioned ice pack

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, said. He said the company’s portable hot/cold wrap is designed for general athletic recovery. But, he says, they are also good enough to replace the post-surgical ice machine, which are expensive, unwieldy, and you go through a ridiculous number of bags of ice.


The thermoelectric wraps, introduced at the Highway1 accelerator’s Demo Day in San Francisco, 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 $250 to $300.
