China unveils an electric-shock wristband for staying awake

A Canadian company, WAT Medical, together with its China-based division, has released a gadget meant to replace coffee and energy drinks. The device, called the eCoffee Energyband, uses mild electric shocks to help users stay alert.

The band features two electrode pads that rest against the inner side of the wrist. According to the manufacturer, the device delivers electrical impulses that stimulate blood flow, keep the brain engaged, and improve concentration.

Each jolt is said to deliver an effect roughly comparable to a cup of coffee, though the company’s COO, Xu Haojie, stressed that the goal is not to eliminate caffeine entirely:

The purpose of inventing this eCoffee Energyband is not to replace coffee. Coffee is great, but it’s not always suitable for the afternoon or evening. But we still have the need to feel refreshed during those times.

So far, there is no independent evidence proving the effectiveness of this specific product. The company instead points to broader scientific studies on how electrical stimulation affects nerve cells.

Because electrical pulses carry risks, the manufacturer advises against wearing the bracelet on the same wrist for long periods. Users are instructed to switch wrists every three hours, as the shocks can temporarily numb parts of the hand — including the fingertips.

The eCoffee Energyband retails for 120 dollars.
