如果 Surface 筆是電容式,那不就也無法使用了。
我是不太相信 Surface 筆是電容式啦。

Wacom and n-trig are both EMR Based, the difference between them is where the electronics live, on a Wacom the electronics live in the Digitizer and the pen is the passive receiver that breaks the field. On the n-trig it is the reverse, the pen has the active electronics, this is why there is a Quad-A battery in the pen (it is also why n-trig devices get better battery life and are thinner)
n-trig devices currently out there include the SP3, Sony DUO 11 and 13, Sony Tap 11, Flip 15, Acer R7 (2013 Model), Fujitsu Q702 and Q550 and Q552, Motion CL-900, HP Slate 500 and Slate 2, HTC Flyer (Android), Dell XT 1 and 2.
Synaptics and Amtel have created a new technology called Active Capacitive and currently doesn't give the best results, although Amtel has improved greatly in their v. 2 pen found on the new HP ElitePad 1000 G and Propad 610. Currently the only Synaptics Pens I'm aware of are on the Dell Venue Pro line (8 and 11).

Biggest surprise? N-Trig is active capacitive. I though it was an EM system like Wacom's - but with a battery rather than relying on the tablet to emit charging pulses.

Active Capacitive Stylus: 1) Precision: in the past I have seen some not so good implementations here, but I am so pumped to see our current results in Pro3. We really did move the mark here. The Pen is really much more precise, linear, and linear across the entire device. The first comment I hear from artists when they use the device, is how precise the pen is.
