Lausanne, Switzerland, April 27, 2017

Today, ActLight presented the next generation Heartrate Sensor for wearables, featuring a remarkable 80% reduction in power consumption compared to what is currently available on the market, and still delivering the same performance. The Heart rate sensor is based on ActLight’s proprietary Dynamic PhotoDiode (DPD) technology and has been developed in co-operation with a global MedTech semiconductor vendor and École polytechnique fédérale de Lausanne (EPFL).

In existing smartwatches and wearables, up to 80% of the power consumption is related to heart rate monitoring when it is activated. A new generation of sensors, developed by ActLight in close co-operation with EPFL, provides high precision heart rate monitoring with significantly reduced energy consumption. This will result in much improved battery lifetime in future smartwatches as well as allowing for extended use of heart rate sensing features related to sports and wellbeing. Already tested and calibrated, ActLight’s heart rate sensor is ready to be produced in large series to equip next generation wearables.

“Increased interest in fitness and wellness – has necessitated more affordable, precise, wearable sensing options. Our technology offers unique competitive advantages to our partners when compared to existing photodiodes used in wearable heart rate solutions” stated Serguei Okhonin, PhD, CEO of ActLight

”Today’s smartwatches and wearables fall short of meeting customer requirements when it comes to  heart rate measurement precision and application battery life time. ActLight is now working with a number of partners to bring this technology into consumer electronics and MedTech grade solutions. We are open for IP licensing of our patented DPD technology that we own 100%” Mr. Okhonin continued.

Detailed results of the project and the ActLight DPD heart rate sensor can be obtained on request.

Lausanne, Switzerland, November 9, 2016

ActLight, a Swiss photonics technology firm known for its breakthrough Dynamic PhotoDiodes (DPD), has announced a project of next-generation sensors for low- energy heartrate sensing for wearable devices in cooperation with ON Semiconductor, driving innovation in energy efficient electronics.

“The healthcare industry is becoming more reliant on new methods to monitor and treat patients. This – along with an increased interest in fitness and wellness – has necessitated more affordable, precise, wearable sensing options,” commented Jakob Nielsen, Senior Manager, Consumer Health Product Line at ON Semiconductor. “Today’s smartwatches and wearables fall short of meeting customer expectations in regards to heartrate measurement precision and application battery life. Working with ActLight, we will help to bring next-generation heartrate sensors to the market that will address these requirements, and deliver a full sensing solution for integration in a multitude of MedTech and consumer electronics applications.”

“Our technology offers unique competitive advantages to our partners when compared to existing Photodiodes used in wearable heartrate solutions,” stated Serguei Okhonin, PhD, CEO of ActLight. “These include lower power consumption, simplified electronics, and smaller footprints, making it perfectly suitable for miniaturized wearable devices. We are happy to have support from ON Semiconductor and to share the potential of our heartrate sensing technology,” Mr. Okhonin continued.

ActLight among best cleantech companies

grafik_navigation_oben_logo_pmeAccording to PME magazine ActLight is among best cleantech companies taking 17th place among TOP 100 swiss start-ups.

PME magazine:

Efficacité numérique

Selon l’Office fédéral de l’énergie, les centres de calcul suisses consomment près de 2000 gigawatt/heures d’électricité par année, soit plus de la moitié de la production d’une centrale atomique comme Mühleberg. Sans compter que le transfert de données et les terminaux consomment eux aussi. Du coup, les technologies qui permettent plus d’efficacité sont bienvenues. Trois des cinq start-up actives dans les cleantechs travaillent sur des innovations représentant un grand progrès en matière de consommation: L.E.S.S. (1er rang), Actilight (rang 17) et Kandou Bus (rang 46). Sous la direction de son CEO Sergueï Okhonin, ActiLight a développé une technologie qui transforme la lumière en courant électrique et le courant en lumière. Elle permet de produire des cellules solaires petites mais efficaces pour alimenter des senseurs et autres outils connectables à l’Internet. Par ailleurs, Actilight permet la fabrication de senseurs lumineux ultra-efficaces qui mesurent par exemple le rythme cardiaque sur une Smartwatch. Suivant l’application, ces senseurs consomment jusqu’à dix fois moins d’électricité que les produits habituels.

Les cinq meilleures cleantechs:

  1. L.E.S.S. (rang l)
  2. Bcomp (rang 4)
  3. Actlight (rang 17)
  4. Bluetector (rang 40)
  5. Kandou Bus (rang 46)
