ALGRA LTD, founded in 1959, is a Swiss company based in Merenschwand. It is one of the world's leading manufacturers of custom-made printed plates, panels and input systems. The company specializes in keyboards based on the piezoelectric effect. Decades of experience, patented technologies, modern production facilities and thrive for perfection make ALGRA a unique partner for companies with exceeding demand in function, durability and design.
ALGRA offers two different technologies for piezoelectric-based input systems: Dynapic® and Dynasim®. Both technologies enable to mass-produce vandal-resistant keyboards that can withstand more than ten million switching cycles. The keyboards are extremely slim and have homogeneous surfaces with an attractive appearance thanks to a wide choice of applicable material, such as metal, glass, polymers and more.
Constructed to have nearly no mechanical movement during key operation, the multilayer laminate structure is based on a piezoelectric membrane or screen-printed piezoelectric polymer composites. ALGRA's keyboards are used in various applications, such as kitchen appliances, parking ticket systems, medical devices, industrial machineries, food processing systems and more.
ALGRA has developed inks to suit different material surfaces, like anodized aluminum, as well as the piezo lacquer for the Dynasim® technology. ALGRA's vital focus on technology enables their engineers to extend boundaries in creating unique input systems, fronts and plates.
Dynapic® Wireless, ALGRA's new self-powered piezoelectric switch, demands no cables and no battery. It reflects ALGRA's creative engineering combined with its traditional attributes: durable, robust and sleek in design.
MicroGen Systems, Inc. is developing a suite of products based on its proprietary piezoelectric vibrational energy harvester (PZEH) technology. These low cost, long lifetime (>20 years) Micro-ElectroMechanical Systems (MEMS) are micro-power sources that extend rechargeable battery lifetime or will eliminate the need for batteries altogether. Applications include consumer, military, industrial and commercial industries.
Arveni sas is a privately held start-up, dedicated to piezoelectric energy harvesting, located near Grenoble (France). Arveni has developed its proprietary technology, protected by 7 patents so far. Arveni's team is made up of 3 highly skilled engineers, and we are focused on the most demanding applications. Arveni's products exist in 3 variants:
We will welcome customers, sales representatives, VCs and labs to our booth !
Joulefusion Limited is developing a range of non-contact microgenerators that harvest energy from the motion of nearby conductive surfaces.
The patent pending technology enables the local provision of regulated electrical power (initially in the 10mW to 1W range) for sensors, wireless sensor nodes, actuators, led lighting and other low power electronic devices.
A wide variety of applications and markets is envisaged as the devices will harvest energy from either rotary or linear motion. Furthermore, the motion may be continuous, oscillatory or even transient; for example a rotating wheel, a suspension element or a metallic target passing infrequently.
