If your partner is an early riser and you are rudely awoken by their alarm every morning, a new gadget could help you lie in.

The alarm clock, called Wakē, rouses individuals from their slumber one at a time using a focused beam of light and sound.

The wall-mounted device creates a 'personal sunrise' and emits focused ultrasonic waves to wake up each person in bed individually without disturbing their partner.

An alarm clock called Wakē rouses individuals from their slumber one at a time using a focused beam of light and sound. It can pivot to make sure it targets a person accurately, even if a couple are cuddled up

It uses a white LED to slowly illuminate the area around a sleeper's face to gently wake them up, with the aim of making them feel alert faster.

Instead of relying on cameras, the device uses a sensor to pick out individuals using body heat. 

It also has built in rechargeable batteries and a Wi-Fi connected processor so it works with a phone app that's used to differentiate between sleepers.

Mounted on a wall, the gadget pivots to send a focused beam of sound towards one sleeper that is emitted by a parametric speaker.

Parametric speakers use ultrasonic waves to create a very narrow, audible beam, which should only be heard by one sleeper, allowing their partner to continue to doze.

Wakē uses a parametric speaker, like a laser beam of sound, to deliver 'focused, soothing sounds that start quietly, and grow louder. Parametric speakers use ultrasonic waves to create narrow, audible beams. This diagram shows how the Wakē gadget works

At the same time, an LED light grows brighter to simulate sunlight, encouraging a sleeper to wake up more naturally.

'Wakē uses a parametric speaker (like a laser beam of sound) to deliver focused, soothing sounds that start quietly, and grow louder slowly as the light beam grows brighter,' according to the device's Kickstarter page.  

'Since Wakē's light and sound is aimed at you, your partner can rest peacefully while you wake up energised.'

The device has been invented by Los Angeles-based firm Lucera Labs. 

It is hoping to raise $100,000 (£66,934) on the crowdfunding site to put the alarm clock into production.

The Wakē app (three screenshots are shown) works like a regular alarm clock app so users can tell it which side of the bed they sleep on and how and when they want to wake up

'Once you're awoken, Wakē will reposition itself should you roll over and shut itself off when you get up,' the company continued.

'You can always snooze or deactivate any alarm using the Wakē app.'

The Wakē app works like a regular alarm clock app so users can say how and when they want to wake up, hit the snooze button and, importantly, tell the device which side of the bed they sleep on.

The alarm costs $250 (£167) to pre-order on Kickstarter and is due to ship in September. 

Using a traditional alarm clock or mobile phone alarm can be annoying for couples who wake up or need to get up for work at different times, as one of them cannot carry on sleeping (illustrated with a stock image)
