AdapTronics Bets EIC Accelerator Money on Electrostatic Grippers

The satellite capture methods in use today, as AdapTronics lists them, each depend on one feature of the target: an adapter ring, a thruster nozzle, a magnetic coupling. AdapTronics, a 2022 spin-off of the University of Bologna, proposes to replace that with a film. Its Electro Active Adhesive Layer (EAAL) is a flexible sheet of printed electronics that becomes adhesive on command through electrostatics and lets go when it is switched off. The company says the same pad holds conductive and insulating, rigid and soft, flat and curved objects, which in principle lets a robot grip a metal panel, a thermal blanket or a packaged product without changing tools.

The EIC Accelerator selected the space version, SpacEAAL, in the October 2025 cut-off for blended finance, under the challenge on in-space servicing and robotics. CORDIS records an EU contribution of €2,499,999 for a project running from 1 July 2026 to 30 June 2028, with the stated aim of taking the gripper from technology readiness level 6 to 9 through an in-orbit validation mission. Four months into the project, the hardware exists and has been tested on the ground at ESA; the flight has not happened.

How a film holds a satellite

Electroadhesion works by charge: a high voltage on electrodes in the film induces opposite charges in the surface it touches, and the two attract. The company's slides give the controller's output as 4,000 volts at 2 milliamps, and its website says the principle and materials suit vacuum and microgravity. The ESA article of 23 April 2026 describes AdapTronics' devices as credit-card-sized multilayer Kapton films that draw about 1 watt while activating, which takes 10 milliseconds, and about 10 milliwatts to keep holding. The same film runs a low-voltage sensing mode that detects proximity and contact, which the company uses to trigger the grip.

For space, the selling point is that the target needs no fixture. The company's Clean Space Days slides list three current approaches, a robotic arm on a launch adapter ring, a probe inserted into a thruster nozzle and magnetic coupling, citing Northrop Grumman's MEV-1 and MEV-2, Astroscale's ELSA-d, ESA and D-Orbit's RISE and the Italian Space Agency's IOS. The slides call them "proven to be effective" but improvable in versatility and complexity. A pad that sticks to whatever surface it touches would, if it works in orbit, also reach satellites and debris that were never built to be serviced.

How strong the grip is depends on which source is read, and the figures do not agree. The company's website says a credit-card-sized layer lifts an average of 10 kg, tested to ISO 8295. L'Espresso reported in January 2024 that a single patch lifts more than 20 kg. The Emilia-Romagna startup directory says two credit-card-sized patches lift up to 50 kg. ESA and the November 2025 funding coverage say "several kilograms". The company's own vacuum test gives 3 kg for a 40 by 40 mm pad. Surface material, pad size and test method are not stated consistently, so the numbers cannot be lined up against each other.

What ESA's flat floor showed

The test that matters for the EIC project took place at ESA's ORBIT facility at ESTEC in the Netherlands, a 43 square metre floor where air-bearing platforms float almost without friction, simulating microgravity in two dimensions. According to ESA, a platform carrying the gripper caught and pulled a second platform standing in for a target satellite of more than 200 kg. ESA does not give the test date.

The detail comes from AdapTronics engineer Riccardo Mazzotti's presentation at ESA's Clean Space Days on 1 July 2026. The campaign tested four gripper versions against four target surfaces: flat anodised aluminium, a 120-degree edge, a 700 mm aluminium cylinder and a flat multilayer insulation frame in aluminised Kapton. On flat aluminium, a single gripper held on after impact in all 48 attempts, at misalignments of up to 90 mm and 20 degrees, and in three thruster runs stayed attached through 20-newton pulses. The contact sensor triggered correctly in 87% of 15 runs and early in 13%, and missed none.

These are the company's figures, presented at an ESA event, not an ESA evaluation, and the slides call them a "preliminary validation". The forces were modest: the slides report that the gripper sustained 3 newtons of pull after impact and 20 newtons during the thruster manoeuvre, and they do not say what an operational capture would require. The slides say the full results will be presented at the 2026 International Astronautical Congress and submitted to a peer-reviewed journal; a search on 4 November 2026 found neither. Earlier conference papers by Mazzotti appear in the programmes of IAC 2024 and IAC 2025.

An industrial product beside the space one

The company does not only build for orbit. Its website lists industrial automation, pick-and-place, sorting and fruit handling, and its slides show the gripper replacing suction cups in packaging machines at the IPACK-IMA 2025 fair and a labelling product at Interpack 2026. The product is sold as a one-time AT-Controller, a 24-volt unit that plugs into a machine's digital inputs and outputs, plus EAAL-Chuck pads that the company describes as recurring consumables. The slides gave CE certification dates of Q1 2026 for a Lite controller and Q3 2026 for a Full version; a web search on 4 November 2026 found no announcement of either certification.

No customer is named in any source reviewed. The company's July 2026 slides claim "20+ LOIs, 2 paid dev. contracts" without saying who signed them. An undated entry in the Emilia-Romagna directory lists two industrial logistics pilots, also unnamed. CompanyReports.it, a data aggregator that says its figures are not taken directly from the company register, lists 2025 revenue of €296,090, a loss of €386,938 and staff costs of €716,548; the filed accounts themselves were not obtained for this article.

The money

AdapTronics says on its website that it closed a pre-seed round of €685,000 in August 2023. In November 2025 it raised €3.15 million in a round led by 360 Capital with Galaxia, the aerospace technology transfer hub of CDP Venture Capital, and Obloo Ventures, which had also backed the pre-seed, according to tech.eu and Teleborsa. The stated uses were production capacity, a pilot plant and European sales. Earlier, the company was among the first Italian startups to win ESA Spark funding in February 2025, for an amount not disclosed.

The EIC selection was announced in February 2026. I3P, the Turin incubator, and the University of Bologna report it as a €2.5 million grant, chosen from more than 900 applications from 32 countries. The award was for blended finance, but no source names an EIC Fund equity investment, and none was found in a search on 4 November 2026. In December 2025 SpaceNews, as republished, listed AdapTronics in NATO DIANA's 2026 cohort under resilient space operations, which the company's slides also state.

Why the EU is paying for it

The challenge that funded SpacEAAL is titled, in CORDIS, "innovative in-space servicing, operations, space-based robotics and technologies for resilient EU space infrastructure". The policy background is debris. ESA's Zero Debris Charter, first signed by twelve countries in May 2024, aims for missions to be "debris neutral in space by 2030", and the European Commission's EU Space Act proposal of 25 June 2025 would require end-of-life disposal and manoeuvrable spacecraft. Removing or servicing objects that were never built for it needs a way to catch targets without predefined docking interfaces, the problem the company's Clean Space Days abstract sets out to address. Whether an electrostatic pad is that way will be settled by the flight, not by the policy.
