DextrES
Electrostatic braking and fingertip feedback for virtual grasping
Keep in mind ETH press release says up to40 N, while the research abstract states20 N; the narrower paper figure is retained and the discrepancy disclosed.

How price order works
Lowest recorded store prices take priority over announced or launch prices, within the selected source market. Currencies use the dated EUR reference rates. Deposits and recurring charges are excluded from price order; missing prices stay last. Original price records remain visible.

Battery claims use different conditions and are not a controlled benchmark. “Not verified” is an evidence gap, not a missing feature. Prices are dated regional snapshots. Deposits, bundles and historical launch prices are labelled. Brightness measurement methods and battery workloads vary by manufacturer.
