Dracula manufacturing unit will get Semtech go, preps for mass OPV IoT manufacturing


France-based Dracula Applied sciences, creating low-light energy-harvesting know-how for passive (battery-less) LoRaWAN-based IoT connectivity, has stated its new manufacturing facility in Valence in southeastern France has handed an audit by US-based Semtech for high quality, security and sustainability, and is able to roll. The agency stated final October the manufacturing unit, providing 2,500 metre-square of ground area with capability to provide as much as “150 million sq. centimetres” of natural photovoltaic (OPV) gadgets per 12 months, will begin “high-volume” manufacturing in “early 2024”

It has the potential to realize that quantity “per 12 months per shift”, it stated this week. “This achievement marks a pivotal step in ramping up the corporate’s manufacturing capability,” it stated of the Semtech overview. The California chip agency – which owns and licences the LoRa bodily layer know-how, which is the idea for the favored LoRaWAN protocol – is an investor in Dracula Applied sciences, since a €5.5 million funding spherical in 2022. Dracula Applied sciences has additionally obtained €5 million in funding from the French authorities, as a part of its France 2030 reindustrialization technique.

The brand new manufacturing unit on the firm’s dwelling in Valence, dubbed the Inexperienced Micropower Manufacturing facility, aligns with European rules to part out non-rechargeable batteries in IoT gadgets. It’s the world’s largest manufacturing unit devoted completely to the manufacturing of OPV modules, its proprietor stated. It’s “totally automated” and “optimised”, and its operation marks “the start of the top for typical batteries”, it stated. Dracula Applied sciences has began to recruit over 60 further workers to the location. It would have 250 workers by 2030, it stated.

OPV know-how attracts energy in murky circumstances, resembling in warehouses or factories, the place the luminous flux per unit space (lux), which measures illuminance, goes as little as 500. Outside gentle registers at nearer to 10,000 lux; the agency’s LAYER-branded OPV modules, introduced for advertising functions as a bat-shaped photovoltaic printout, work at 200 lux, and even all the way down to 100 lux. They use LoRaWAN; it has a prototype OPV tracker, doing the rounds for a couple of 12 months, that makes use of a reference module from Semtech and a cloud stack from The Issues Industries (TTI). 

It additionally has a brand new multi-band Lora module developed with Semetch, Murata, and e-peas. In April, it introduced compatibility with the most recent STM32U0 line of ultra-low energy microcontrollers (MCUs) from STMicroelectronics, geared for low-power industrial IoT purposes, which gives “up-to 50 p.c” discount in vitality consumption versus “earlier MCUs”, it stated. The LAYER OPV product will be printed in any dimension, relying on the required energy output, onto an 0.3mm adhesive sticker on a daily inkjet printer utilizing particular OPV ink.

The brand new manufacturing unit will deal with this course of, in response to “rising demand”, it stated. The corporate has a new electrical vitality storage resolution, known as LAYERVault, to retain OPV energy on a single versatile movie and mixed in a two-in-one resolution with its LAYER OPV harvesting know-how. LAYERVault was introduced at CES in Las Vegas in January as a “first-of-its-kind”, which integrates electrical storage with OPV vitality harvesting. It’s a “vital milestone” for the IoT group, the corporate proclaimed.

Brice Cruchon, chief government at Dracula Applied sciences, stated: “Semtech has among the many highest high quality, security, and environmental requirements in its business. Its affirmation is of nice significance for Dracula Applied sciences’ new manufacturing website and can allow us to meaningfully ramp up manufacturing to satisfy our prospects’ wants over the approaching years. This achievement marks an important development in scaling up manufacturing capability to deal with the rising want for our OPV modules.”

Olivier Vendor, technical fellow for wi-fi IP at Semtech, commented: “We’re excited concerning the potential of this facility to advance energy-efficient IoT purposes. This qualification affirms not solely the robustness of Dracula Applied sciences’ manufacturing processes but additionally their dedication to sustainability and innovation. Via manufacturing of OPV modules at scale, we are able to collectively speed up deployment of self-powered gadgets. Decreased reliance on conventional batteries paves the best way for a extra sustainable future.”
