Cornell Chipsats
Cool stuff - though they seem to be talking about silicon substrates (eventually), not thinned silicon chips on aluminum.
IEEE Spectrum, August 2011, Mason Peck
- First sprites, 10g 3.8 cm square (1.5 inch)
6.88 kg/m2 ( 5 gram thinsats, 0.028m2, 0.18 kg/m2)
Dr. Peck speculates: eventually 20μm thick and 7.5mg, 60μm/s2
- 4.5e-10 Newtons
Light pressure is 1367W/m2 / 2.998e8 m/s -> 4.56e-6 N/m2
approx 1e-4 m2 -> 2e-9 m3 -> 3750 kg/m3
ballistic coeff 0.0375 kg/m2
- Lorentz force, charging the chipsats then deflecting in magnetic field
