Sasuraibito in Japan has developed a pyroelectric sensor. His page is a
little hard to read, but the diagrams and photos are very good.

Both of these are hard with the available power at the sensor plug. I think
I've read that the Poloroid Ultrasonic range sensor has peak current
requirements of over an Amp. However, it has an operating range that is
longer than you really need for Mindstorms robots. I wonder if the sound
generator in the RCX could produce enough sound to be used for this type of
thing. Kinda like the way people have used the IR transmitter to make a IR
prox sensor.
BTW. Dennis Clark developed a self contained Infrared range sensor.
